Testing out your code with a SciPy example and I am getting the incorrect inverse. Am I doing something wrong? SciPy: ```python >>> from scipy.fft import fft, ifft >>> import...

This PR does a few small things: - It improves the fft function documentation - It adds a normalize argument to the fft and dft functions. Normalization is disabled by...

fftr is an very handy library. I am porting some code from numpy to nim and utilize the fftr libaray. Forward FFT works well, but IFFT seems not match with...

Hi! I wrote the following code : ``` import fftr, std/[math, sequtils] import strutils let # Square wave # signal = (0..1023).mapIt(complex64(if(it < 512): 1.0 else: -1.0)) # Saw wave...
