2D Interpolation of Irregular Grid Data

I have 2D data of f(x,y) at irregular "grid" points and
I wanted to do some interpolation so as to get this
data on a regular(and denser) grid, so that I can
further manipulate it with available packages.
Is anyone aware of any package/software/code
that can help me do this.
(i.e. the mathematica and matlab functions
only work with regular grids)

Thanks for the help.
