GEN10 — Generate composite waveforms made up of weighted sums of simple sinusoids.
These subroutines generate composite waveforms made up of weighted sums of simple sinusoids. The specification of each contributing partial requires 1 pfield using GEN10.
size  number of points in the table. Must be a power of 2 or powerof2 plus 1 (see f statement).
str1, str2, str3, etc.  relative strengths of the fixed harmonic partial numbers 1,2,3, etc., beginning in p5. Partials not required should be given a strength of zero.
Note  


Here is an example of the GEN10 routine. It uses the files gen10.csd.
