void load_quadrature(World &world, const char *dir)
Collective routine to pre-load and cache the quadrature points and weights.
Definition: legendre.cc:146
void legendre_scaling_functions(double x, long k, double *p)
Evaluate the first k Legendre scaling functions.
Definition: legendre.cc:90
This header should include pretty much everything needed for the parallel runtime.
