#include <complexFFT.H>

List of all members.

Public Methods
	complexFFTData (int sz)
	Constructor with all memory to be allocated internally.
	~complexFFTData (void)
	Deconstructor.
void	switchData (complexFFTData *d)
	Use this to change associated fft data (for fft'ing).
int	limitHalfPowerSpec (double lim)
	Limits the maximum to 'lim' and returns the last fft bin with max.
int	getSize ()
	Returns the number of elements in the input and output arrays.
int	compPowerSpec ()
	This function computes the power spectrum and returns the max bin.
Public Attributes
int	size
	Specifies the size of the data array.
fftw_complex *	in
	the input and output arrays
fftw_complex *	out
	the input and output arrays
fftw_real *	power_spectrum
	the power_spectrum array
double	totalPower
	The total power (summed) of the power spectrum as used in the method compPowerSpec.
