xfft

Defined in xtensor/misc/xfft.hpp

template<class E>
inline auto xt::fft::fft(E &&e, std::ptrdiff_t axis = -1)

1D FFT of an Nd array along a specified axis

Parameters:

  • e – an Nd expression to be transformed to the fourier domain

  • axis – the axis along which to perform the 1D FFT

Returns:

a transformed xarray of the specified precision
