Let's avoid using this define for clarify.

Is there some reference implementation we could additionally cite here?

| Real step = M_PI/log(N+1); | ||
| int num_rows = _C/step+1; // Number of rows. +1 because need to include the first row which is the 0th multiple of step | ||
| int P = matrix[0].size(); |
