List of all members.

Public Member Functions

 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
fftw_real * power_spectrum
 the power_spectrum array
double totalPower
 The total power (summed) of the power spectrum as used in the method compPowerSpec.
