This script generates a table of twiddle factors you can directly use with the complex FFT functions.

Usage

This script runs with Scilab (http://www.scilab.org/), Scilab is the free software for numerical computation.
The following variables can be modified in the script:

• N_TWIDDLE_FACTORS: to specify the maximum length of the FFT you want to use with this table.
• BITS: the number of bits of a data (16 or 32).
