Function realdft¶

`function` realdft(const univector<T, Tag> &) dft ¶

template <typename T, univector_tag Tag>
univector<complex<T>> realdft(const univector<T, Tag>& input)

Performs the direct (forward) real-to-complex DFT using a cached plan.

Template parameters
T	Floating-point type ( `float` or `double` ).
Tag	Storage tag of the input univector.

Parameters
input	Input real univector of \(N\) samples.

Returns
	Output complex univector of \(\frac{N}{2}+1\) samples (Hermitian-symmetric spectrum).

Note

No scaling is applied.
