I would like to get a maximum of a matrix in intervals inside for loop.

Matrix K has dimension (N,3,3). I like to have a matrix P (Max of K) between N 1 to 10, and then update it again with K and find the maximum at N 10 to 20.

So far I can get the maximum of the matrix K but can't update it in each interval.

Thanks in advance.



L=3
N=30
Interval=10
