Hello,

Hello,

Present version of Intel(R) MKL supports 1D spline based interpolation only. Data Fitting component of the library provides routines for spline construction and relevant computations such as interpolation, search and integration. We support linear, quadratic, cubic and user-defined splines.

Are you interested entirely in 2D interpolation, or 1D is also of your use?

Also, can you please provide, if possible, additional details behind your usage model of 2D interpolation such as problem dimension, type of spline (only cubic or other types are possible as well), number of interpolation sites, data types (integer, floating-point), etc? Is 2D interpolation is a compute intensive part of your application?
