Detailed Description

template<size_t Dim>
class intrp::Cardinal< Dim >

Interpolates by doing partial summation in each dimension using one-dimensional interpolation.

The one-dimensional matrices used to do the interpolation depend upon the Spectral::Basis used in each dimension:

For a Chebyshev or Legendre basis, the matrices are given by intrp::fornberg_interpolation_matrix at the quadrature points of the source_mesh. (These are equivalent to those returned by Spectral::interpolation_matrix.)
For a Fourier basis, the matrix is given by intrp::fourier_interpolation_matrix at the quadrature points of the source_mesh
