Problem 42858. Block average ignoring NaN values
Given a matrix, calculate the block average of each disjoint sub-matrix while ignoring NaN values. 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 = blknanavg(A,subsz)
Example:
A = [1 2 3 4 5 6 7 8 NaN]; subsz = [1 3]; B = [2 5 (7+8)/2];
Hint: this is related to Problem 42856. Block average.
