Hello, I am trying to use @jit for optimizing a function using numpy.fft.fft Below is my code import numpy as np import math from numba import njit def fft_analysis(x, fs): # function to transform time domain signal to frequency domain # using Fast Fourier Transform y = np.array(np.fft.fft(…

hi @krishnamoparthi , this part tells you what you need to know Untyped global name ‘fft_analysis’: Cannot determine Numba type of <class ‘function’>”. You are using a function called fft_analysis which is not jitted, so it cannot be used inside a jit function.

Thank you. I have numpy.fft.fft used in the fft_analysis. Does numba support numpy.fft.fft

Hi @krishnamoparthi This issue tracks the general “FFT support” request: Support for np.fft.fft, np.fft.ifft etc. · Issue #5864 · numba/numba · GitHub , the main issue is this: Support for np.fft.fft, np.fft.ifft etc. · Issue #5864 · numba/numba · GitHub Hope this helps?

Hello @luk-f-a Thank you for the help
