Subject:  * Add a few constraints on the FFT size parameters and make the parameters
X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;h=469f2a3f9d9e4ddd11474e336ab756ca9ebb000c;p=matthijs%2Fprojects%2Fmontium-fft.git

 * Add a few constraints on the FFT size parameters and make the parameters
   abide by those constraints (we're now doing 4 16-point FFT's).
