This [Lua] module provides a binding to [stb_fft], a fast fourier transform library 

suitable for power of 2 and non-power of 2 written by ZhiHan Gao.

All functions in this module are operating on [carray] arrays of *double* or *float* 

element data type. 

Examples:

   * [`example01.lua`](./examples/example01.lua) - demonstrates complex fourier transform

   * [`example02.lua`](./examples/example02.lua) - demonstrates real fourier transform
