List of all members.

Public Methods
	realFFTData (int sz)
	All memory to be allocated internally.
	realFFTData (int sz, fftw_real *inp, fftw_real *outp)
	input and output data arrays are to be allocated by another process
	~realFFTData (void)
	Deconstructor.
int	limitHalfPowerSpec (double lim)
	Limits the maximum to 'lim' and returns the last fft bin with max.
int	getSize (void)
	Returns the number of elements in the input and output arrays.
int	getHalfSize (void)
	Returns the number of elements in the power spectrum array.
fftw_real	findMaxIn (void)
	Returns the maximum input variable.
void	findMaxMinPowerBins (void)
	Fills the max and min power spectrum bins.
int	compPowerSpec ()
	This function computes the power spectrum and returns the max bin.
int	sqrtPowerSpec ()
	This function computes the square root of the power spectrum and returns the max bin.
void	zeroFFTData (void)
	This function zeros the output data array (out).
Public Attributes
int	size
	Specifies the size of the data array.
int	minPowerBin
	Specifies the minimum and maximum power bins as used in the methods findMaxMinPowerBins and compPowerSpec.
int	maxPowerBin
	Specifies the minimum and maximum power bins as used in the methods findMaxMinPowerBins and compPowerSpec.
fftw_real *	in
	the input, output and power_spectrum arrays
fftw_real *	out
	the input, output and power_spectrum arrays
fftw_real *	power_spectrum
	the input, output and power_spectrum arrays
double	totalPower
	The total power (summed) of the power spectrum as used in the method compPowerSpec.
