To clarify your problem, a small example of code or input and output values would be helpful.

Matrices cannot have errors. They contain just values.

I guess, that you want to find the differences between two matrices:

a = rand(3,3) + i*rand(3,3);
b = a;
b([1,3,5]) = rand(1,3) + i*rand(1,3);
find(a ~= b)
% >> [1, 3, 5]

Then FIND replies the linear indices - see SUB2IND and IND2SUB.

Does this solve your question or did you mean something else?
