Reduce the size of isosurface output

I use isosurface to extract levels: fv=isosurface(X,Y,Z,V,value)

That is, I want to use the vertex/face info generated as the starting structure (meshed surface) for the next step in the simulation. Unfortunately, isosurface puts out O(10^5) vertices/faces for a simple problem, done at a reasonable grid size (resolution).

Does anyone know of a Matlab-based method to reduce the number of mesh element in a 3D surface mesh?

BTW: Using a larger grid spacings from meshgrid does not provide me with the resolution of features on the surface.
