Expand description
One dimensional discrete Fourier Transform.
ยงParams
a
: The input array.n
: Size of the transformed axis. The corresponding axis in the input is truncated or padded with zeros to matchn
. The default value isa.shape[axis]
.axis
: Axis along which to perform the FFT. The default is -1.
