Function Documentation

fftw_typename()

template<typename realT >

std::string mx::math::fft::fftw_typename

(

)

Return a string corresponding the fftw real floating point type.

This is used for wisdom filenames.

Template Parameters

realT

the real floating point type.

fftw_wisdom_filename()

template<typename realT >

std::string mx::math::fft::fftw_wisdom_filename

(

)

Create the mxlib standard wisdom filename for the type.

Looks for the environment variable MXFFTW_WISDOM. If not found, then pwd "./" is used.

Template Parameters

realT

is the real floating point type.
