adding time consuming bar(waiting bar) to MatLab GUI for push button

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,

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

can anyone help me .......

Is resizeingDONTDELETE a script that runs for one step using the variable step to determine what to do?

[Sahan Priyanga]

i am going to use that script for read scanned image and segment it's objects

[Walter Roberson]

When you run('resizeingDONTDELETE.m') does that do all of the work, or does it only do the work for a single image numbered step ?

can you please help me to do that task with respect to time () i mean that i want to show the time taken for process (with dynamically update) in second/minute/hours )

[Sahan Priyanga]

let consider the following case,

it should be show the time (I mean time in number {let at 1s as 00 00 01, at 2s as 00 00 02 and finally 00 t_total 55 (assume) like wise})

[Stalin Samuel]

h = waitbar(0,'Please wait...');
tic
t_total = 55;
while toc < t_total 

  %%your calculation

  waitbar(toc / t_total )
end
close(h)
