[Matlab] Figure and axis options

In Matlab, if you type get(gcf) of get(gca) you will get a list of the current properties of the given axis or figure. Also, set(gcf) or set(gca) will list all available properties and the legal options you can set. This is true for other objects also. I tend to use figures and axes regularly and forget these option and so I am listing them here.

[Matlab] Colors and Symbols for ploting in loops

Sometimes it is easier to use a loop to plot something rather than manually typing plot many times. The problem is that all of the lines will have the same color and all the symbols will be the same. This code easily applies color to plots in a loop.

[Matlab] User Interface Functions

One easy method for creating a user interface is a question dialog. This can easily be used with the switch function to run different sections of code.

SelectFunction = questdlg('What do you want to do?', ...
                'Select Function', ...
                'Get data from images', 'Get Amplitude information from data','Plot displacement vs. time','Get data from images');
switch SelectFunction
   
%% Input data from images
    case 'Get data from images'

      'Stuff'

    

    case 'Get Amplitude information from data'

      'more stuff'

A more complex but useful process is this:

function UserInterfaceExample

% User Interface Example

% Creates a box with buttons which execute functions

 

    clear;clc;close all;

    height = 250;

    width = 200;

    figure

    set(gcf,'Position',[1000 height+200 width height],'Menubar','none')

   

    uicontrol('Style', 'pushbutton', 'String', 'Say Hi',...

            'Position', [50 height-50 100 20],...

            'Callback', @Function1);

   

    uicontrol('Style', 'pushbutton', 'String', 'Say Bye',...

        'Position', [50 height-100 100 20],...

        'Callback', @Function2);

   

    uicontrol('Style', 'pushbutton', 'String', 'Draw a Line',...

        'Position', [50 height-150 100 20],...

        'Callback', @Function3);

   

    uicontrol('Style', 'pushbutton', 'String', 'Draw Shapes',...

        'Position', [50 height-200 100 20],...

        'Callback', @Function4);

end

function Function1(src,evt)

    clear;clc;close all;

    fprintf('HI')

end

function Function2(src,evt) 

    clear;clc;close all;

    fprintf('Bye!') 

end

    

function Function3(src,evt)

    clear;clc;close all; 

    figure

    line([2 5],[2 5])

end

function Function4(src,evt)

    clear; clc; close all;

    figure

    rectangle('Position',[200 200 300 500],'Curvature', [0 0])

    rectangle('Position',[10 10 300 500],'curvature',[1,1])

    axis square

end

other functions:

uicontrol

uigetdir

uigetfile
inputdlg

errordlg
helpdlg
listdlg
msgbox
questdlg
uiresume
uiwait

end

[Matlab] Adding ASCII Charecters for abvanced ploting

Some times in Matlab one may want to add some charecter in the code. Here is an example:

Lets say you want to plot several variables with similar names (like A1, A2, A3) using a for loop as such:

A1 = 0:5;
A2 = 5:10;
A3 = 10:15;

for i = 1:3

    eval(['plot(A',num2str(i),')'])

    hold on

end

This will work but all of your plots will have the same line type, symbol color etc. Now it you want to add different colors to a plot you can use strings to define the colors. But using the eval function creates problems because you must create a string within a string. usually you can use this notation:

String = 'Here is another "string" in this string'

However with the eval function this does not work for me. However, ASCII charecters can be created using the char command. So to add colors to the plot:

A1 = 0:5;
A2 = 5:10;
A3 = 10:15;

colors = [1 0 0; 0 1 0; 0 0 1];
for i = 1:3
    eval(['plot(A',num2str(i),',',char(039),'color',char(039),',colors(i,:))'])
    hold on
end

A list of ASCII character codes are found here:
http://www.asciitable.com/

use the char() command to insert the charecters

Here is a good list of colors and symbols to use with these plots:

symbol = {'o','s','^','v','<','>','d','p'};
colors = [  0   0   0
            0.8 0   0
            1   0   0
            1   0.6 0
            0   0.6 0
            0   0   1
            0   0   0.6
            0.8 0   0.8
                        ];

Styles for BibTeX4word - Custom and modified .bst files using windows

I am using Microsoft Windows 7 (and Windows XP at home) and I use Word to create documents.  You must first be familiar with Word, Jabref, MikTex, and Bibtex4word before this will make sense. Start by reading the Bibtex4word documentation. These three programs will allow you to automatically create bibliographies in word.

Here is a manual for Miktex

Below is a list of style types that I use regularly:

• ieeetr/cn^s - good for most conferences
• phaip/cn[]^s - actual APL (AIP) file but use et al. for over 5 name which APL does not allow.
• phjcp/cn[]^s - like APL and does not use et al. but has lower caps in names. ~ this can be made to match APL almost perfectly if you highlight all of the references, press ctrl+d, uncheck the small caps option.
• phnflet - like APL without et al. but uses all caps and DOI in wrong place.
• 
  
• rsc/cn[]^s - RSC reference type such as Lab on a Chip
• achemso/cn[]^s - America chemical society

Other people have more comprehensive lists of styles:

• http://www.ee.ic.ac.uk/hp/staff/dmb/perl/index.html
• http://web.reed.edu/cis/Help/LaTeX/bibtexstyles.html 

Most Journals have a style. It is best to find one that already exists because modifying and creating them is a real pain.

Modifying .bst files:

The first thing to know about this is that it is really anoying. I have been trying to figure this out for weeks and still have had little luck. There are many many websites that give information, but must of the time it is not that helpful.

Finding my .bst files: This is much more difficult that it seems. I though they would be in the "Program Files/miketex2.8" folder. Nope. I finally found them in:

"C:\Users\UserName\AppData\Roaming\MiKTeX\2.8\bibtex" ~ in Windows 7
"C:\Documents and Settings\UserName\Application Data\MiKTeX\2.8\bibtex\bst" ~ in Windows XP

[Matlab] Loading Large Data Sets

The Old Way to Load DataSets

Lots of my time consists of analyzing huge sets of files recorded by and oscilloscope or some other device. Typically, I would try to use the same name for each file with a number at the end that increase each time. Then I can write a loop to load all of the files, then do analysis and create plots. This causes its own problems for several reasons such as: several loops must be used for different regions of the data (tek0000n for n = 1-9; tek000nn for nn = 10-99; tek00nnn for nnn = 100-999; etc) and broken loops when a single file in the data set is a different length or mission, and many other issues. Such a sustem looks like this where many conditional loops are used to fix the problem:

if m <10 & n < 10

   for i = 1:n

       Temp = dlmread([File,'/',File,'-0000',num2str(i),'.txt'],'\t',[17 0 3664 1]);

       Frequency(:,i) = Temp(:,1);

       Absorption(:,i) = Temp(:,2);

   end

end

if m <10 & n < 100 & n > 10

   for i = 1:9

       Temp = dlmread([File,'/',File,'-0000',num2str(i),'.txt'],'\t',[17 0 3664 1]);

       Frequency(:,i) = Temp(:,1);

       Absorption(:,i) = Temp(:,2);

   end

           

   for i = 10:n

       Temp = dlmread([File,'/',File,'-000',num2str(i),'.txt'],'\t',[17 0 3664 1]);

       Frequency(:,i) = Temp(:,1);

       Absorption(:,i) = Temp(:,2);

   end

end

       

if m <10 & n < 1000 & n > 100

   for i = 1:9

       Temp = dlmread([File,'/',File,'-0000',num2str(i),'.txt'],'\t',[17 0 3664 1]);

       Frequency(:,i) = Temp(:,1);

       Absorption(:,i) = Temp(:,2);

   end

           

   for i = 10:99

       Temp = dlmread([File,'/',File,'-000',num2str(i),'.txt'],'\t',[17 0 3664 1]);

       Frequency(:,i) = Temp(:,1);

       Absorption(:,i) = Temp(:,2);

   end

           

   for i = 100:n

       Temp = dlmread([File,'/',File,'-00',num2str(i),'.txt'],'\t',[17 0 3664 1]);

       Frequency(:,i) = Temp(:,1);

       Absorption(:,i) = Temp(:,2);

   end

end

       

if m > 10 & n < 1000 & n > 100

   for i = m:99

       Temp = dlmread([File,'/',File,'-000',num2str(i),'.txt'],'\t',[17 0 3664 1]);

       Frequency(:,i) = Temp(:,1);

       Absorption(:,i) = Temp(:,2);

   end

           

   for i = 100:n

        Temp = dlmread([File,'/',File,'-00',num2str(i),'.txt'],'\t',[17 0 3664 1]);

        Frequency(:,i) = Temp(:,1);

        Absorption(:,i) = Temp(:,2);

   end

end

       

if m < 10 & n > 1000

   for i = 1:9

       Temp = dlmread([File,'/',File,'-0000',num2str(i),'.txt'],'\t',[17 0 3664 1]);

       Frequency(:,i) = Temp(:,1);

       Absorption(:,i) = Temp(:,2);

   end

          

   for i = 10:99

       Temp = dlmread([File,'/',File,'-000',num2str(i),'.txt'],'\t',[17 0 3664 1]);

       Frequency(:,i) = Temp(:,1);

       Absorption(:,i) = Temp(:,2);

   end

           

   for i = 100:999

       Temp = dlmread([File,'/',File,'-00',num2str(i),'.txt'],'\t',[17 0 3664 1]);

       Frequency(:,i) = Temp(:,1);

       Absorption(:,i) = Temp(:,2);

   end  
end

Read Directory and Load

Recently, google helped me discover a better method where you can actually tell matlab to read and record the files names in a specific folder. The, so long as all the data is the same length, a single loop can be used to import all of the data in a single folder. Here is an example:

clear;clc;close all

cd ..
Temp = dir('Data');
Temp2 = {Temp.name};
FileName = Temp2(3:end);

for i = 1:length(FileName)
    Temp = dlmread(['Data/',char(FileName(i))],',',[14 0 10013 2]);
    time = Temp(:,1);
    ch1 = Temp(:,2);
    ch2 = Temp(:,3);
    save(['[Matlab]/MData/DataSet',num2str(i),'.mat'],'time','ch1','ch2')

end

return

The dir command reads the folder \Data, and a structure cell is created with the information for each file. Since I only care about the name, that cell can be extracted and trimmed. Then a single loop can be used to load all of the data into a useful format. To prevent errors if the files are not the same length, each data set is save in its own .mat file. These files can be quickly loaded in Matlab for later use.

Loading several .mat files

Once all of the data is stored in separate .mat files, this data can be easily accessed and plotted. It one were to plot the first 5 data sets that were loaded above, this code would perform the operation:

for i = [1:5]
    Str = ['MData\DataSet',num2str(i),'.mat'];
    load(Str)
    eval(['time_',num2str(i),' = time;'])
    eval(['ch1_',num2str(i),' = ch1;'])
    eval(['ch2_',num2str(i),' = ch2;'])

end

figure

hold on
        

for i = 1:5
    eval(['plot(time_',num2str(i),',ch1_',num2str(i),')'])

end

hold off

I realize that there are many non standard matlab functions here, but I encourage people to learn these functions. They have been very useful for me in performing some more advanced actions.
