I have MATLAB R2017a. When I open contourplots from Matlab R2010 they look fine but I cannot save them due to the above error message. How to fix that?
Thanks

I just encountered the same problem
looking into the Z-matrix of contour plot, I found there is a Inf.
Remove this Inf (set to zero or NaN) then everything works well for me, for example
z(isinf(z)) = nan;
