I'm looking for the function of pyFFTW that has exactly same result with FFT of MATLAB.
I already tried with some functions of pyFFTW like bellows.
x is 1D array, type: np.float32
Python 3.5.2:
a = fftw.n_byte_align_empty(x.size, 16, 'complex128')
b = fftw.n_byte_align_empty(x.size, 16, 'complex128')
fft_object = fftw.FFTW(a, b)
fft_object(x)
or
fft_object = fftw.builders.fft(x)
fft_object()
MATLAB:
fft(x)
But, there are a little differences(about 0.000001) by comparison with MATLAB's FFT.
Is there no way to get the exactly same result with MATLAB's FFT??
- Version of python : 3.5.2
- Version of pyFFTW : 0.10.4
- Version of numpy : 1.12.0
- Version of MATLAB : 8.3.0.532 (R2014a)
Thanks!
