Hi All
How can I put a push button that has the same function of Ctrl+C in MATLAB workspace ? that can kill an execution immediately ?

Use this undocumented MATLAB command to send a Ctrl+C to the MATLAB command window
com.mathworks.mde.cmdwin.CmdWinMLIF.getInstance().processKeyFromC(2,67,'C')

No, it just equivalent to the code in my answer.
The only option which I can think of which might work in this case is to use the OutputFcn property of fsolve(). That outputFcn gives the option to terminate the fsolve() based on a condition. You just need to figure out a way to communicate button press to the outputFcn. For example, using a global variable (a simple approach but can cause issues in the long term) or pass a handle class to OutputFcn and change one of its properties based on the button press event. This is a general outline of the method. You can try it to see if it works.

That's not a good idea. It would be better to abort your code gracefully. Like have a check box on your GUI that says "Finish Now" and if the user checks it, it gets out of your function gracefully and leaves your program running. Like if you're in a loop
for k = 1 : 1000000
% Some intensive code.....
% Now see if user wants to bail out:
if app.chkFinishNow.Value
return; % or break. to get out of the function (if return is used), or the for loop (if break is used).
end
end
Doing it like you asked is very bad programming practice in my opinion, and probably most everyone else's also.

No. If it were checked, it would abort immediately. What you'd do is this:
% Make visible to user and make sure it's unchecked.
app.chkFinishNow.Value = false;
app.chkFinishNow.Visible = 'on';
for k = 1 : 1000000
% Some intensive code.....
% Now see if user wants to bail out:
if app.chkFinishNow.Value
break; % Get out of the function (if return is used), or the for loop (if break is used).
end
end
% At the end of the loop, make the Finish Now checkbox unchecked and invisible.
app.chkFinishNow.Value = false;
app.chkFinishNow.Visible = 'off';
