Subject:  * Prefix all algorithm parameters with PARAM_ so we can still use variable
X-Git-Url: https://git.stderr.nl/gitweb?p=matthijs%2Fprojects%2Fmontium-fft.git;a=commitdiff_plain;h=7b57bd2ad91ccd7b8faff015adf1cbe87ddff3ea

 * Prefix all algorithm parameters with PARAM_ so we can still use variable
   names such as 'n'.
