WebMar 17, 2024 · This means if you provide an int for the dim argument to rfft2 instead of a tuple it will run without complaint, but will return a 1D FFT along that dim. Similarly if you provide a 3-tuple it will happily return a 3D FFT. This is unexpected behavior as it should … WebThe Fast Fourier Transform (FFT) is an efficient algorithm to calculate the DFT of a sequence. It is described first in Cooley and Tukey’s classic paper in 1965, but the idea actually can be traced back to Gauss’s unpublished work in 1805. labor with pitocin

WebApr 16, 2024 · Sorted by: 2 The problem is that data is a dictionary and when you unpack it the way you did ( X_train, Y_train = data) you unpack the keys while you are interested in the values. refer to this simple example: d = {'a': [1,2], 'b': [3,4]} x, y = d print (x,y) # a b So you should change this: X_train, Y_train = data into this: WebJul 28, 2024 · 1. That is a character vector. You cannot fft () a character vector. If you need to apply fft to the ASCII codes that are used for the letters 'd' 'a' 't' and so on, then fft (double (f), n) .
