Index matrix exceeds dimensions - Using pad array

Hello, I'm working on an adaptive histogram equalization problem that requires me to pad an image on all 4 sides using the symmetric argument.

I attached my code (Problem2_RUNME)

I also attached the algorithm I am trying to implement.

This is the error that I'm getting: Index exceeds matrix dimensions.

Error in Problem2_RUNME (line 19) if B(x,y) > B(i,j)

Hello Matthew,

The reason you are getting this error is because your win_size to to large. The range of x is 1 to 600 while that of y is 1 to 800. For i and j the range is 1 to 1089(33*33). Ensure that your win_size*winsize is less than the size of image and this error will not be thrown.
