Why do I get error message :"error using contourc. Countour values must be finite" ?

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;

Please include the code used to replace inf values with 0s or NaNs to show the solution.
