Detailed Description

A base class for a Matlab-like wavelet bank.

Author: John Clyne

Version: $Revision$

Date: $Date$

The MatWaveBase class is a base class for building Matlab-inspired wavelet filter banks. In many cases the methods provided behave similarly - in some cases indentically - to the Matlab Wavelet Toolbox version 4 command of the same name.

Member Function Documentation

size_t VAPoR::MatWaveBase::approxlength ( size_t sigInLen ) const

Returns length of approximation coefficients generated in a decompostition pass

This method returns the number of approximation coefficients generated by one decomposition pass through the filter bank for a signal of length, sigInLen.

Parameters

[in] sigInLen Length of input signal (number of samples)

Return values

length On success returns the number of coefficients. A negative int is returned on failure.

See also: MatWaveDwt::dwt()

size_t VAPoR::MatWaveBase::coefflength ( size_t sigInLen ) const

inline

Returns length of coefficients generated in a decompostition pass

This method returns the number of coefficients (approximation plus detail) generated by one decomposition pass through the filter bank for a signal of length, sigInLen.

Parameters

[in] sigInLen Length of input signal (number of samples)

Return values

length Returns the number of coefficients.

		size_t	sigInY,
		size_t	sigInZ
	)		const

Definition at line 158 of file MatWaveBase.h.

size_t VAPoR::MatWaveBase::detaillength ( size_t sigInLen ) const

Returns length of detail coefficients generated in a decompostition pass

This method returns the number of detail coefficients generated by one decomposition pass through the filter bank for a signal of length, sigInLen.

Parameters

[in] sigInLen Length of input signal (number of samples)

Return values

length Returns the number of coefficients.

See also: MatWaveDwt::dwt()

int VAPoR::MatWaveBase::dwtmode ( const string & mode )

Set the discrete wavelet extension transform mode

Parameters

[in] mode Valid values for mode are: "zpd", "symh", "symw", "asymh", "asymw", "sp0", "sp1", "spd", "ppd", and "per".

Return values

status a non-negative int is returned on success

int VAPoR::MatWaveBase::dwtmode ( dwtmode_t mode )

Set the discrete wavelet extension transform mode

Parameters

[in] mode

Return values

status a non-negative int is returned on success

See also: dwtmode_t

const string VAPoR::MatWaveBase::dwtmode ( ) const

Get the current discrete wavelet extension transform mode

Parameters

[out] mode Current mode

Return values

status a non-negative int is returned on success

dwtmode_t VAPoR::MatWaveBase::dwtmodeenum ( ) const

inline

Get the current discrete wavelet extension transform mode

Return values

mode

Definition at line 84 of file MatWaveBase.h.

bool& VAPoR::MatWaveBase::InvalidFloatAbortOnOff ( )

inline

Set or get the abort-on-invalid-float flag

When set, the presence of input data containing invalid floats - floats for which the math.h isfinite() function does not return true - results in the abnormal termination of the method. If the flag is not set invalid floats are set to zero. By default the flag is not set.

Return values

flag	A reference to the abot-on-invalid-float flag

Definition at line 189 of file MatWaveBase.h.

int VAPoR::MatWaveBase::wavelet ( const string & wname )

Set the current wavelet

Change the current wavelet to the one specified by wname.

Parameters

[in] wname Name of wavelet.

Return values

status a non-negative int is returned on success

const WaveFiltBase* VAPoR::MatWaveBase::wavelet ( ) const

inline

Get the current discrete wavelet

Return values

wavelet

Definition at line 106 of file MatWaveBase.h.

string VAPoR::MatWaveBase::wavelet_name ( ) const

inline

Get the current discrete wavelet name

Return values

name

Definition at line 100 of file MatWaveBase.h.

size_t VAPoR::MatWaveBase::wmaxlev ( size_t s ) const

Returns maximum wavelet decompostion level

This method returns the maximum level decomposition of a signal of length, s. This is the maximum number of times that a single level decomposition can be applied to a signal

Parameters

[in] Length of input signal

Return values

length Returns the maximum number of decompositions.
