MATLAB: How to Run an m.file from GUIDE push button

guiguidemfileneural networkpush buttonpushbutton

I am using GUIDE to build my GUI. I need a push button to run an m.file which consists of my neural network. Please advise what should I put in the CreateFcn column if I want to run my m.file by pressing the push button. Thanks.

Leave the CreateFcn alone for this task. Put the call to the M-file in the callback for the pushbutton. The callback is the function that is called when the button is pushed. For example, if the name of your M-file is myfile.m, then put this line in the callback for the pushbutton:

myfile;

Now if you need to pass argments to myfile, or get a return value, then we will have to add to this basic syntax.

Your function is calling itself without approaching any convergance or something that will allow it to end. Therefore it will run forever and eventually out of memory (hence the error). Try splitting it up into a script and a function as so:

Script:

 %creating window of plot from -5 to 50 using stepsize 0.25 for t x-axis
 %t should be on the x axis, v should be on the y axis
 k=0; 
for i= -5:.25:50
    k = k+1;
    t(k)=i;
    v(k)=vPieceWise(t(k));
end 
plot(t,v);
 
figure
plot(t,v);
hold on

Function:

%Part A: Mfile function to compute v as a function of t
function v = vPieceWise(t)
 if (t < 0)
        v = 0;
    elseif (0 <= t)&&(8<=16)
        v = -5*t+10*t.^2;
    elseif (8<=16)&&(t<=16)
        v = 624 - 3*t;
    elseif (t<=16)&&(t<=26)
        v = 12*(t-16).^2+36*t;
    elseif (26<t)
        v = 2136*exp(-0.1*(t-26));
 end
