The size of X must match the size of Z or the number of columns of Z.

What are the dimensions of your x2, y2, and M variables? You've got a size mismatch between your x2 and M variables. For example:

Z = peaks;
contour(1:size(Z,1),1:size(Z,2),Z);
% is ok, but
contour(1:size(Z,1)-1,1:size(Z,2),Z);


generates the error that you're seeing.
