MATLAB Compiler generated exe's can't read/use plain m files.

The only way to have interchangeable data is through a file, e.g. mat file.

Compiled Applications Do Not Process MATLAB Files at Runtime

The MATLAB Compiler was designed so that you can deploy locked down functionality. Deployable MATLAB files are suspended or frozen at the time MATLAB Compiler encrypts them—they do not change from that point onward. This does not mean that you cannot deploy a flexible application—it means that you must design your application with flexibility in mind. If you want the end user to be able to choose between two different methods, for example, they both must be compiled in.

The MCR only works on MATLAB code that was encrypted when the component was built. Any function or process that dynamically generates new MATLAB code will not work against the MCR.

Some MATLAB toolboxes, such as the Neural Network Toolbox™ product, generate MATLAB code dynamically. Because the MCR only executes encrypted MATLAB files, and the Neural Network Toolbox generates unencrypted MATLAB files, some functions in the Neural Network Toolbox cannot be deployed.

Similarly, functions that need to examine the contents of a MATLAB function file cannot be deployed.HELP, for example, is dynamic and not available in deployed mode. You can use LOADLIBRARY in deployed mode if you provide it with a MATLAB function prototype.

Instead of compiling the function that generates the MATLAB code and attempting to deploy it, perform the following tasks:

1. Run the code once in MATLAB to obtain your generated function.

2. Compile the MATLAB code with MATLAB Compiler, including the generated function.

Tip: Another alternative to using EVAL or FEVAL is using anonymous function handles. If you require the ability to create MATLAB code for dynamic run time processing, your end users must have an installed copy of MATLAB.

 

 

The only way is using mat file...

 [FileName,PathName] = uigetfile('*.mat','Prepare mat file'); % a is in the .mat file

fullname = fullfile(PathName,FileName);

load(fullname) 

set(handles.text1,'String',num2str(a(1:end)))

%checking delta

chekdel=strcat('if delx(1)<=tol(1)&delx(2)<=tol(2);','disp([xopt Fopt]);'...

    ,'disp(delx);','else;','del=delx*rasio;','delx=del;','eval(eksplorasi);'...

    ,'end;');

%repeating success step

ulsuk=strcat('while Fopt<F;','disp([xopt Fopt]);','for i=1:n;',... 

    'x(i)=xopt(i)+delx(i)*tanda(i);','end;','F=fungsi(x(1),x(2));',... 

    'if F<=Fopt;','xopt=x;', 'Fopt=F;','else;','break;','end;','end;',... 

    'eval(eksplorasi)');

%exploration:

eksplorasi=strcat('for ep=1:n;','tanda(ep)=0;','x(ep)=xopt(ep)+delx(ep);',... 

    'Fd=fungsi(x(1),x(2));','if Fd<=Fopt;','xopt(ep)=x(ep);','Fopt=Fd;','tanda(ep)=1;',... 

    'else;','x(ep)=xopt(ep)-delx(ep);','Fd=fungsi(x(1),x(2));','if Fd<=Fopt;',... 

    'xopt(ep)=x(ep);','Fopt=Fd;','tanda(ep)=-1;','end;','end;','end;','disp([xopt Fopt]);',... 

    'if abs(tanda(1))>0|abs(tanda(2))>0;','eval(ulsuk);','else;','eval(chekdel);',... 

    'end;'); eval(eksplorasi);

function [] = pb_call(varargin)

h = varargin{1}; % Get the caller's handle.

col = get(h,'backg');  % Get the background color of the figure.

set(h,'str','RUNNING...','backg',[1 .6 .6]) % Change color of button. 

% The pause (or drawnow) is necessary to make button changes appear.

% To see what this means, try doing this with the pause commented out.

Syntax

Description

filename = uigetfile displays a modal dialog box that lists files in the current folder and enables you to select or enter the name of a file. If the file name is valid and the file exists, uigetfile returns the file name as a string when you click Open. Otherwise uigetfile displays an appropriate error message, after which control returns to the dialog box. You can then enter another file name or click Cancel. If you click Cancel or close the dialog window, uigetfile returns 0.

Examples

The following statement displays a dialog box for retrieving a file. The dialog box lists all MATLAB code files within a selected directory.uigetfile returns the name and path of the selected file in FileName and PathName. uigetfile appends All Files(*.*) to the file types when FilterSpec is a string.

[FileName,PathName] = uigetfile('*.m','Select the MATLAB code file');

The following figure shows the dialog box with the file type drop-down list open.

To create a list of file types that appears in the file type drop-down list, separate the file extensions with semicolons, as in the following code. uigetfile displays a default description for each known file type, such as "Model files" for Simulink^® .slx and .mdl files.

[filename, pathname] = ...
     uigetfile({'*.m';'*.slx';'*.mat';'*.*'},'File Selector');

If you want to create a list of file types and give them descriptions that are different from the defaults, use a cell array, as in the following code. This example also associates multiple file types with the 'MATLAB Files' and 'Models' descriptions.

[filename, pathname] = uigetfile( ...
{'*.m;*.fig;*.mat;*.slx;*.mdl','MATLAB Files (*.m,*.fig,*.mat,*.slx,*.mdl)';
   '*.m',  'Code files (*.m)'; ...
   '*.fig','Figures (*.fig)'; ...
   '*.mat','MAT-files (*.mat)'; ...
   '*.mdl;*.slx','Models (*.slx, *.mdl)'; ...
   '*.*',  'All Files (*.*)'}, ...
   'Pick a file');

The first column of the cell array contains the file extensions, while the second contains your descriptions of the file types. In this example, the first entry of column one contains several extensions, separated by semicolons, which are all associated with the description 'MATLAB Files (*.m,*.fig,*.mat,*.mdl)'. The code produces the dialog box shown in the following figure.

The following code lets you select a file and then displays a message in the Command Window that summarizes the result.

[filename, pathname] = uigetfile('*.m', 'Select a MATLAB code file');
if isequal(filename,0)
   disp('User selected Cancel')
else
   disp(['User selected ', fullfile(pathname, filename)])
end

This code creates a list of file types and gives them descriptions that are different from the defaults. It also enables multiple-file selection. Select multiple files by holding down the Shift or Ctrl key and clicking on additional file names.

[filename, pathname, filterindex] = uigetfile( ...
{  '*.mat','MAT-files (*.mat)'; ...
   '*.slx;*.mdl','Models (*.slx, *.mdl)'; ...
   '*.*',  'All Files (*.*)'}, ...
   'Pick a file', ...
   'MultiSelect', 'on');

As mentioned previously, uigetfile does not open the file or files you select.

You can use the DefaultName argument to specify a start path and a default file name for the dialog box.

uigetfile({'*.jpg;*.tif;*.png;*.gif','All Image Files';...
          '*.*','All Files' },'mytitle',...
          'C:\myfiles\my_examples\gbtools\setpos1.png')
