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. Is there any good reference or test code?Please help me. thanks you!

Can anyone point to me about the interpolating splines in 3D space coding procedure by FORTRAN or C++. Thanks
