Hi, 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 plan_many option. 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. Thanks gvsaradhi
