Introduction

This library provides a set of functions for computation derivatives using spectral methods. The lib depends on FFTW library. The library is compatible with W-SLDA Toolkit however, it can be used as standalone lib. It is written in C99 standard.

Name convention

Generic name of a function is wderiv_operation_xd_t, where:

• wderiv: fixed, function belongs to wderiv lib,
• operation:
  • dfdx
  • dfdy
  • d2fdx2
  • laplace
  • grad
  • ...
• x:
  • 1 for 1D problems
  • 2 for 2D problems
  • 3 for 3D problems
• t:
  • r for real problems
