Dear all

I want to interpolate a function f(x,y) on a two dimensional grid. I have the values of funtion on grid points. I want to interpolate the value of funtion, its fist derivative w.r.t x and y, its second drivative w.r.t. x and y, and mixed derivative at a known point in the grid.

I want to use cubic spline interpolation. I want a fortran code for the above problem.

Can you help me or guide me with suitable references.
