Remove values from matrix based on another matrix

Hi,

I have matrix A with the dimensions of 45 x 73 x 28. I have matrix B with the dimensions of m x n x p. I would like to remove all the rows in B that contain any values exceeding the corresponding values in A? This means rows to be deleted from B would have m>45 and/or n>73 and/or p>28. Basically A would be the limit for B.

I'm sure this is a common problem and someone must have asked before but I was not able to find the asnwer. Could someone please help?

B=B(1:45,1:73,1:28)

Thanks, Azzi. Since the dimensions of A are not static, I did the following:

B=B(1:size(A,1),1:size(A,2),1:size(A,3))

However, this gave me an error: Index exceeds matrix dimensions. Not sure why.

Try

siz=min([size(A);size(B)])
B=B(1:siz(1),1:siz(2),1:siz(3))
