Problem 42856. Block average

Solve Later

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)"

To fix the "Error using VisibleTest1 (line 4)", could you change your first line as "function b = blkavg(A,subsz)"?

*facepalm* Thank you. I feel like quite the idiot right now for not noticing that error.
