Constructor & Destructor Documentation

Matrix::Matrix (   )  [inline]

Create uninitialized matrix.

Matrix::Matrix (  DBL  d[3][3]  )  [inline]

Create matrix from array. Parameters: d  3x3 array holding the matrix entries

Matrix::Matrix (  int  d  )  [inline]

Create matrix with same entries. Parameters: d  value for all elements

---

Member Function Documentation

void Matrix::applyFromLeft (  const Matrix &  m  )

Matrix multiplication. Calculate A = M*A. Parameters: m  the matrix M

Matrix Matrix::generateRotationMatrix (  const Vector3 &  v  )  [static]

Create rotation matrix. Parameters: v  x,y,z rotation values in radians. Rotating is first done around x then around y and finally around z axis

Matrix Matrix::generateScaleMatrix (  const Vector3 &  v  )  [static]

Create scaling matrix. Elements of v on the diagonal and zeros elsewhere. Parameters: v  x,y,z scaling value

bool Matrix::invert (   )

Invert matrix. Returns: false if matrix is singular else (that means inversion was successful) true

const DBL& Matrix::operator() (  int  i, int  j )  const [inline]

Access to matrix elements in constant matrix.

DBL& Matrix::operator() (  int  i, int  j )  [inline]

Access to matrix elements.

void Matrix::transpose (   )

Transpose matrix.

void Matrix::zero (   )  [inline]

Set all matrix entries to zero.
