I have created MatLab GUI and it execute matlab script by clicking button on GUI.

now I want method for showing time consuming for run of that script

following code shows how I did that so far

function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
run('resizeingDONTDELETE.m');
end

I find a code for show wait bar but it is not worked!!!!

h = waitbar(0,'Please wait...');
steps = 1000;
for step = 1:steps
run('resizeingDONTDELETE.m');
    waitbar(step / steps)
end
close(h)

here I want the results as follow,

  • when push button is clicked wait button should be open and should show time as zero
  • time should be increased with time taken to executing the script
  • after executing wait bar should be disappered

can anyone help me .......

your waitbar call should be somewhere inside resizeingDONTDELETE.m, if it has a for loop, not outside. – Itamar Katz
what happened it contain no of for loops – Sahan Priyanga
how can it modify in order to display the prograss (I mean when half of script is executed then bar remain at it middle point and like wise) – Sahan Priyanga
see my answer, it becomes too long for a comment – Itamar Katz

A waitbar is useful if your script is divided to some intermediate steps (not necessarily a for loop), where you can indicate a progress in (or before) each intermediate step. In pseudo-code, assuming you have 4 intermediate steps:

  • Main Script
    • waitbar(0/4)
    • do intermediate step 1
    • waitbar(1/4)
    • do intermediate step 2
    • waitbar(2/4)
    • do intermediate step 3
    • waitbar(3/4)
    • do intermediate step 4
    • waitbar(4/4)

Otherwise, if your script is a 'black box' which starts and terminates without giving you access to some intermediate steps - you cannot use waitbar in a useful way.
