Function Documentation

fft()

template<typename ReturnVector = cvec, typename InputVector = cvec>

ReturnVector theoretica::signal::fft ( const InputVector &  x, bool  inverse = false  )

inline

Compute the Fast Fourier Transform of a set of data points.

Bit reversion is used on the indices to simplify the resulting calculations.

Parameters

x	The set of data points in the time domain
inverse	Whether to run the inverse transform (defaults to false)

Returns

The data in the frequency domain

ifft()

template<typename ReturnVector = cvec, typename InputVector = cvec>

ReturnVector theoretica::signal::ifft ( const InputVector &  k )

inline

Compute the Inverse Fast Fourier Transform of a set of data points.

Bit reversion is used on the indices to simplify the resulting calculations.

Parameters

k	The set of data points in the frequency domain

Returns

The data in the time domain
