Member Function Documentation

template<class T >

bool lti::luSolution< T >::apply	(	const matrix< T > &	B,
		matrix< T > &	X
	)

onCopy version of apply.

Solves the set of n linear equations A x=b where x is the i-th _column_ vector of X and b the i-th _column_ vector of B. For use with multiple right sides b of a set of equation systems Ax=b, the matrix decomposition is computed only on calling apply the first time. After that the existing decomposition will be used until calling setParameters.

template<class T >

bool lti::luSolution< T >::apply ( matrix< T > & B )

onPlace version of apply.

Solves the set of n linear equations A x=b where x is the i-th _column_ vector of X and b the i-th _column_ vector of B. For use with multiple right sides b of a set of equation systems Ax=b, the matrix decomposition is computed only on calling apply the first time. After that the existing decomposition will be used until calling setParameters.

bool lti::luSolution< T >::apply	(	const vector< T > &	b,

onCopy version of apply.

Solves the set of n linear equations Ax=b. For use with multiple right sides b of a set of equation systems Ax=b, the matrix decomposition is computed only on calling apply the first time. After that the existing decomposition will be used until calling setParameters.

template<class T >

bool lti::luSolution< T >::apply ( vector< T > & b )

onPlace version of apply.
