Detailed Description

Performs 1-D discrete wavelet transforms (DWT)

This class is basically a wrapper for the GSL wavelet implementation. Refer to GSL documentation for more info.

Member Function Documentation

void Pulsar::WaveletTransform::set_order ( int o )

inline

Set wavelet order.

Implemented values (as of GSL 1.11) are:

void Pulsar::WaveletTransform::set_type ( const gsl_wavelet_type * t )

inline

Set wavelet type.

Possible types (as of GSL 1.11) are:

All types can have _centered appended to their name to get centered versions.
