Try this in your pushbutton callback

startingTime = tic;
% some image processing code...
elapsedTime = toc(startingTime);
handles.edit1.String = sprintf('%.2f', elapsedTime);

Instead of edit1, use whatever you have for the "Tag" property of the edit box.

still doesn't work. this is some of my function.

tic
ticBytes(gcp);

      J = 3;

      a(1:N,1:M,1,1:J+1) = 0;
      dx(1:N,1:M,1,1:J+1) = 0;
      dy(1:N,1:M,1,1:J+1) = 0;
      d(1:N,1:M,1,1:J+1) = 0;
  tocBytes(gcp)
  toc

it appear time for me in command window. but i cannot make it appear in my GUI that i have make. i want to show the time taken to user through GUI, not command window. :(

You keep doing the same thing and totally ignoring what people suggest.

The toc function has an output. Assign it to a variable as is shown in both answers.

sorry i'm not ignoring what you guys suggest. i have tried it before i'm replying here but i still didn't get what i want it to be. sorry again and for your information, i'm not major in this course so i'm not really understand about all the suggestions, but I had google and search about it before. It's okay then. Thank you for all the suggestions. I'll try again. :)

Look at my code again. It gets the elapsed time and sends it to your edit text box.

startingTime = tic;
% some image processing code...
J = 3;
a(1:N,1:M,1,1:J+1) = 0;
dx(1:N,1:M,1,1:J+1) = 0;
dy(1:N,1:M,1,1:J+1) = 0;
d(1:N,1:M,1,1:J+1) = 0;
elapsedTime = toc(startingTime);
handles.edit1.String = sprintf('%.2f', elapsedTime);

Try tic and toc.

[nuh lili]

yes i used tic and toc in my function. it showed me the time, but it was in command window. but i want that time showing im my GUI, not command window

[Benjamin Kraus]

Then you need to capture the output from toc...

t = tic;
% do stuff
sec = toc(t);

The output from toc is the number of seconds since you called tic. No output is displayed in the command window.

[nuh lili]

I used this:

tic

ticBytes(gcp);

tocBytes(gcp)

toc

because i'm using parfor.

and this is the results it showed me in command window:

 BytesSentToWorkers    BytesReceivedFromWorkers
             __________________    ________________________

    Total    0                     0

Elapsed time is 17.192636 seconds.

But, i want this "17.192636 seconds" appear in my GUI. :)

Just put the output from toc it into your edit box string, using num2str, in that case, although I would advise using a text control instead as an edit box is editable which does not make sense if it is reporting run time.
