Problem 42856. Block average
Given a matrix, calculate the block average of each disjoint sub-matrix of the same size. Assume that the size of the matrix along each dimension is an integer multiple of the size of the sub-matrix along the same dimension.
- Input: matrix A and the size of each sub-matrix subsz
- Output: B = blkavg(A,subsz)
Example:
A = [2 0 1 3 5 7]; subsz = [1 2]; B = [1 2 6];
Hint: this is related to Problem 42854. Crunch that matrix!.

It's related to that problem in another way. I'm getting a similar error to Zikobrelli did: "Error using VisibleTest1 (line 4)"
