i am using bicubic spline code for 2D interpolation.
i am getting right interpolation values in between but at boundaries the values are wrong.
i tried natural (1e30) as well as tried by giving first derivative.
but there was no significant improvement.
can anyone guide me by telling how to overcome this problem.
thankyou.
waiting for your responses.

Did you try using Legendre interpolation to set the boundary
conditions ?

hi,
i didn/t try legendre interpolation.
right now i am using bicubic spline.
is it possible to use legendre interpolation boundary condition in bicubic spline.
i have never tried this.
it wud be really helpful if u can guide of how to do it.
thank you.
waiting for ur response.
