How to solve the problem of the index beyond the matrix dimension?

[Ancient4]

Excuse me
I tried using 10 or 200 or 300 pictures, found that the use of too few pictures or too many pictures will have this problem. I would like to ask you, how to solve this?

@Ancient4
Did you change any code?
Or did you apply the code to the other datasets?

First,I chose some pictures from the Market1501 dataset.
Second,I change the code from the prepare.m.Because, when I run the code an error occurred. I found that in line 31, s should be a positive integer, so I removed "-1".

You also need to change the fc channel from 751 to 702.
You may check the baseline code in:
