Detailed Description

Class representing matricies with 3 rows, and 3 columns.

CSIBCMatrix33d objects represent matricies, and define a set of operations which are useful in the context of a matrix. Unlike CSIBCMatrix4x4, there is no method of accessing the matrix data directly, thus it does not matter whether the values are stored in column major, or row major order.

This class uses double precision floating point numbers to store element values. There exists three other matrix classes, CSIBCMatrix44d, CSIBCMatrix4x4 and CSIBCMatrixMNd. They are used to represent 4x4 matricies with double precision floating-point numbers, 4x4 matricies with single precision floating-point numbers, and MxN matricies with double precision floating-point numbers, respectively.

bool GetEigenVectors ( CSIBCMatrix33d &  out_matEigenVectors,
CSIBCVector3Dd &  out_vctEigenValues,
const double  in_dEps = PICO_EPS  
) const

Computes the eigenvectors and eigenvalues of this matrix. Since this method uses floating-point comparison, a threshhold value of in_dEps is used for equality comparison.

Parameters:
out_matEigenVector  Matrix whose rows represent the eigenvectors of this matrix.
out_vctEigenValues  Vector whose components represent the eigenvalues of the corresponding eigenvectors in out_matEigenVector.
in_dEps  Floating-point comparison error range. Defaults to PICO_EPS

bool AreAlmostEqual ( const CSIBCMatrix33d &  in_mat1,
const CSIBCMatrix33d &  in_mat2,
const double  in_dEpsilon = PICO_EPS  
) [friend]

Determines whether all corresponding elements of the matricies in_mat1 and in_mat2 are equal. Since this method uses floating-point comparison, a threshhold value of in_dEpsilon is used for equality comparison.

Parameters:
in_mat1  First matrix for equality comparison.
in_mat2  Second matrix for equality comparison.
in_dEpsilon  Floating-point comparison error range. Defaults to PICO_EPS.
Returns:
bool true if the matricies are equal, false otherwise.
