How to avoid NaN when summing up vectors?

Hi,

Im trying to make some discrete integrals using trapz or even just using riemann sums, but I cant avoid getting NaN as a result. And the vector Im trying to integrate has no NaN values... Matlab can plot it perfectly without problems, values are well bounded but just cant sum up the total value.

Any help?

You could use isnan to find the nans and delete them or interpolate over them.
