Problem 2234. Find and replace the zero array in a matrix
Find the zero array in the matrix and replace it with average of surrounding (adjacent) arrays.
Example:
A =
3 5 7 90 1
5 1 -1 0 2
1 2 3 4 70
23 1 2 3 5

I think you want to write A and not x:
assert(isequal(adjacent_averaging(A),B))

test case #2 and 3 should be corrected. Instead of x, it should be A

What elements do you consider the "surrounding arrays"?

Surrounding arrays apparently are the elements right above, below, left, and right the zero elements. Found out by reverse engineering. The x is still a mystery.

More tests please. A lot of solutions assume that 0 can't be in the first (or last) column.
