Member Function Documentation

◆ apply()

template<class DT >

const Tmat3< DT > & ml::Tmat3< DT >::apply ( MLDblFuncPtr fct )

inline

Applies the function fct to each component.

Definition at line 448 of file mlMatrix3.h.

◆ det()

template<class DT >

DT ml::Tmat3< DT >::det

Determinant.

Definition at line 414 of file mlMatrix3.h.

References DET3.

◆ getIdentity()

template<class DT >

Tmat3< DT > ml::Tmat3< DT >::getIdentity

inlinestatic

Returns the identity matrix.

Definition at line 437 of file mlMatrix3.h.

◆ getMat()

template<class DT >

Tmat3< DT > ml::Tmat3< DT >::getMat ( const double val )

inlinestatic

Returns a matrix filled with values val.

Definition at line 196 of file mlMatrix3.h.

◆ getValues() [1/2]

template<class DT >

void ml::Tmat3< DT >::getValues ( double mat[9] ) const

inline

Copies the contents of *this into mat, row by row.

Note that range and precision of the float values may not be sufficient for the double matrix contents.

Definition at line 382 of file mlMatrix3.h.

◆ getValues() [2/2]

template<class DT >

void ml::Tmat3< DT >::getValues ( float mat[9] ) const

inline

Copies the contents of *this into mat, row by row.

Note that range and precision of the float values may not be sufficient for the double matrix contents.

Definition at line 358 of file mlMatrix3.h.

◆ inverse()

template<class DT >

Tmat3< DT > ml::Tmat3< DT >::inverse ( bool * isInvertible = nullptr ) const

Returns the inverse.

Gauss-Jordan elimination with partial pivoting. If a non-NULL Boolean pointer is passed to isInvertible then true is returned in *isInvertible in the case of a successful inversion or false if the inversion is not possible (function return is the identity then). If a NULL pointer is passed as isInvertible the matrix must be invertible, otherwise errors will occur.

Definition at line 685 of file mlMatrix3.h.

References DCMTree::DT, and ml::MLInverseMatHelper().

◆ jacobi()

template<class DT >

Tmat3< DT > ml::Tmat3< DT >::jacobi	(	Tvec3< DT > &	evalues,
		int &	rots
	)		const

Calculates the Jacobi-Decomposition of 3x3 matrix.

The Jacobi method is deemed to be an absolutely foolproof method for all real symmetric matrices (however a little bit slower than more sophisticated methods as QR decomposition)

Computes all eigenvalues and eigen vectors of a symmetric 3x3 matrix and returns matrix of normalized eigenvectors. evalues[1,..,3] contains the eigenvalues, rots the number of Jacobi rotations that where required.

evalues[i] <-> (eVec[0][i],eVec[1][i],eVec[2][i])

Divides by a constant. Division by zero is not handled and must be avoided by caller.

◆ operator<()

template<class DT >

bool ml::Tmat3< DT >::operator< ( const Tmat3< DT > & ) const
