Hi there,

As far as you know, is it possible to numerical compute the gradient or the laplacian term of a velocity field in matlab?

I try to better explain myself. I mean knowing how to map in a x-y plane some data from an unstructured mesh (as the one from the classic case of the potential cylinder in the OF's tutorial) is there a tool or function in matlab to compute the gradient or the laplacian?
