MATLAB: .exe with inputs

exefunctioninput

Good afternoon,

I am new in MatLab, so I am no familiarized yet with making functions and programs. I have designed these lines to obtain some information from my data file called 'TR007-3_1FL.txt':

fID=fopen('TR007-3_1FL.txt','r');
A=0.017; Po=100;
formatSpec='%f  %f'; sizeSpec=[2,Inf]; datos=fscanf(fID,formatSpec,sizeSpec); close('all');
vexp=datos(1,:);iexp=-1.*datos(2,:);ivexp=iexp.*vexp;jexp=iexp./A;jvexp=jexp.*vexp;
Voc=interp1(iexp,vexp,0)  
Isc=interp1(vexp,iexp,0)

, and now I want to make it an .exe that can be executed on a PC without installing MatLab. I think I have the Compiler Toolbox, but I do not know how to make the program a function that asks me to enter different files names and 'A' and 'Po' parameters for each different file to analyze. Could you please give me any help?

Thank you so much !

use uigetfile() to allow user to pick a file.

use input() to allow user to input a value.

After you test out your new program, run "deploytool" to compile your program to a stand-alone application, assume you have all the Toolbox needed.

Here are my number input snippets. Feel free to modify/adapt:

% Ask user for one integer number.
defaultValue = 45;
titleBar = 'Enter a value';
userPrompt = 'Enter the integer';
caUserInput = inputdlg(userPrompt, titleBar, 1, {num2str(defaultValue)});
if isempty(caUserInput),return,end; % Bail out if they clicked Cancel.

% Round to nearest integer in case they entered a floating point number.
integerValue = round(str2double(cell2mat(caUserInput)));
% Check for a valid integer.
if isnan(integerValue)
    % They didn't enter a number.  

    % They clicked Cancel, or entered a character, symbols, or something else not allowed.

    integerValue = defaultValue;
    message = sprintf('I said it had to be an integer.\nI will use %d and continue.', integerValue);
    uiwait(warndlg(message));
end
% Ask user for two floating point numbers.
defaultValue = {'45.67', '78.91'};
titleBar = 'Enter a value';
userPrompt = {'Enter floating point number 1 : ', 'Enter floating point number 2: '};
caUserInput = inputdlg(userPrompt, titleBar, 1, defaultValue);
if isempty(caUserInput),return,end; % Bail out if they clicked Cancel.
% Convert to floating point from string.
usersValue1 = str2double(caUserInput{1})
usersValue2 = str2double(caUserInput{2})
% Check for a valid number.
if isnan(usersValue1)
    % They didn't enter a number.  
    % They clicked Cancel, or entered a character, symbols, or something else not allowed.
  % Convert the default from a string and stick that into usersValue1.
    usersValue1 = str2double(defaultValue{1});
    message = sprintf('I said it had to be a number.\nI will use %.2f and continue.', usersValue1);
    uiwait(warndlg(message));
end

Perhaps get your numbers from a small GUI like inputdlg() creates:

% Ask user for two floating point numbers.
defaultValue = {'45.67', '78.91'};
titleBar = 'Enter a value';
userPrompt = {'Enter floating point number 1 : ', 'Enter floating point number 2: '};
caUserInput = inputdlg(userPrompt, titleBar, 1, defaultValue);
if isempty(caUserInput),return,end; % Bail out if they clicked Cancel.
% Convert to floating point from string.
usersValue1 = str2double(caUserInput{1})
usersValue2 = str2double(caUserInput{2})
% Check for a valid number.
if isnan(usersValue1)
    % They didn't enter a number.  
    % They clicked Cancel, or entered a character, symbols, or something else not allowed.
  % Convert the default from a string and stick that into usersValue1.
    usersValue1 = str2double(defaultValue{1});
    message = sprintf('I said it had to be a number.\nTry replacing the user.\nI will use %.2f and continue.', usersValue1);
    uiwait(warndlg(message));
end
% Do the same for usersValue2
