Class TransformDirection
source code
Transform (namely integral transform) direction.
In FFT, it is equal to sign of the exponent, that is the backward
transform uses -1, the forward transform +1. This is the opposite sign
convention to FFTW (for instance), so care must be taken when mixing
operations.
Note:
All the enumerated values are defined at the module level,
not the class level. The are just groupped by class here
for easier orientation.
