Functions

fft(x[, fsc, n, axis, overwrite_x])	Performs a 1D FFT of the input array along the given axis.
ifft(x[, fsc, n, axis, overwrite_x])	Performs a 1D IFFT of the input array along the given axis.
rfft(x[, fsc, n, axis])	Performs a 1D FFT of the real input array along the given axis.
irfft(x[, fsc, n, axis])	Performs a 1D IFFT of the input array along the given axis.
fftshift(x[, axes])	Shift the zero-frequency component to the center of the spectrum.
ifftshift(x[, axes])	The inverse of fftshift.
