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
Output is:
B=23.75;

What elements do you consider the "surrounding arrays"?

J-G van der Toorn on 4 Mar 2014

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.
