fft2() [1/2]

template<typename M , require_eigen_dense_dynamic_vt< is_complex, M > * = nullptr, require_not_var_t< base_type_t< value_type_t< M > > > * = nullptr>

Eigen::Matrix< scalar_type_t< M >, -1, -1 > stan::math::fft2 ( const M &  x )

inline

Return the two-dimensional discrete Fourier transform of the specified complex matrix.

The 2D discrete Fourier transform first runs the discrete Fourier transform on the each row, then on each column of the result.

Template Parameters

M	type of complex matrix argument

Parameters

[in]

x

matrix to transform

Returns

discrete 2D Fourier transform of x
