Constructor & Destructor Documentation

Mat3D::Mat3D (  ) 

Constructor for zero matrix.

Mat3D::Mat3D ( double  a11,
double  a12,
double  a13,
double  a21,
double  a22,
double  a23,
double  a31,
double  a32,

Mat3D::~Mat3D (  )  [inline]

Destructor.


Member Function Documentation

double Mat3D::determinant ( void   )  const

Return determinant of matrix.

Mat3D Mat3D::inverse ( void   )  const

Return inverse matrix.

double& Mat3D::operator() ( int  i  )  [inline]

Indexing for matrix.

Returns a reference to i element, where i is the index in row-first order. No checking performed - not a safe function.

const double& Mat3D::operator() ( int  i  )  const [inline]

Indexing for constant matrix.

Returns a reference to i element, where i is the index in row-first order. No checking performed - not a safe function.

const double& Mat3D::operator() ( int  i,
int  j 
) const [inline]

Indexing for matrix.

Returns a reference to (i,j) element, where i is the row and j is the column number. No checking performed - not a safe function.

double& Mat3D::operator() ( int  i,
int  j 
) [inline]

Indexing for matrix.

Returns a reference to (i,j) element, where i is the row and j is the column number. No checking performed - not a safe function.

Vec3D Mat3D::operator* ( const Vec3D x  )  const

Matrix-vector multiplication.
