Hi all,
I am facing a trouble in extracting the indecies from the 3rd dimension of matrix using 'find' function.
for example : time is 251 * 28 * 20, where 20 is the time.
index = find(time>=datenum(2019,02,01)& time<=datenum(2019,02,07));
any help will be apprecited

By default, find() return linear indexes. To convert them to the dimension subscripts, you ind2sub()
index = find(time>=datenum(2019,02,01)& time<=datenum(2019,02,07));
[r, c, p] = ind2sub(size(time), index)
'p' is location in 3rd dimension.

after checking with what I have, it is working!!
The problem is it was taking another set.
Thank you very much Ameer.
