Problem 868. Replace all zeros and NaNs in a matrix with the string 'error'
Given a numeric input matrix A, possibly containing some zero values and some NaNs, replace any occurrences of zero or NaN with the character string 'error'. The output should be a cell array C of the same size as the input matrix. Each cell of the output cell array should either contain the corresponding entry of A if this is not zero or NaN, or the string 'error' otherwise.
Example:
If A = [1 0; NaN 1], then the output C should be the cell array C = {1, 'error'; 'error', 1}.

Any idea why b={1 0; nan 3}; isequal(b,b) gives false?
Don't bother... nan is not equal to nan unless you use isequaln!
