- Parameters
-
[in] nu exponent. [in] dim dimension of the input vectors. [in] m matrix that transforms the lattice. [in] x shift vector. [in] y wave vector. [in] lambda relative weight of the sums in Crandall's formula. [in] reg false for no regularization, true for the regularization. [in] aniso false for no anisotropy, true for the anisotropic variant. [in] alpha multiindex for the derivatives.
- Returns
- function value.
