Nonfinite endpoints or increment for colon operator in index

Hi everyone, someone might have ask before but I didn't find them useful in my case

I'm transforming data from an array to another as below

partialData(1:cx,1:cy,:,1) = data(1:cx,1:cy,s:t);

size(partialData) = 300 X 215 X 901 X 4

size(data) = 300 X 215 X 901

cx, cy, s, t are fix number

so the problem doesn't seems to be matrix size

Moreover, it works for 26 iteration(the code is in a for loop) but later it just comes up this error on 27th iteration

wondering what causes this error and why

thanks in advance!

Please show the code.

@Jimmy Ni: please edit your question and show us the complete error message. This means all of the red text.

Also show us what this displays:

 disp(cx)
 disp(cy)
 disp(s)
 disp(t)
 size(partialData)
 size(data)

We need to see MATLAB printed output.
