I would like to use the fftw bench program to time the following.
Use plan_many_dft from Advanced interface to calculate a bunch of ffts on
a contiguous array of complex numbers. Can some one help me with the
options i need to pass on to fftw bench program to be able to choose
I the readme file, suggestions for inplace and out of place 2d fft
examples are shown. Apparently the program has the option to specify
plan_many. but it is not clear as to how that can be specified.
