bool GaussJordan::Invert (  TNT::Matrix< double > &  A, TNT::Matrix< double > &  AInv )  [static]

Inverts the matrix A which is returned in AInv. This method leaves A untouched. If there is some problem with the input matrix A, we return false. Parameters: A  The input matrix to be inverted. AInv  The resulting inverted matrix. Returns: False if there was some problem during the inversion process. Otherwise, True upon success.

bool GaussJordan::Solve (  TNT::Matrix< double > &  A, TNT::Vector< double > &  b )  [static]

Solves the equation Ax=b using Gauss-Jordan method. You pass in the matrix A and the vector b. Upon return, A holds the inverse of the original matrix A and b holds the solution x = A^-1 * b. In other words, this method destroys both input A and b. Parameters: A  Input Matrix, set to the inverse of A upon return. b  Input vector, set to the solution x upon return. Returns: False If matrix A is singular or some other problem arises. Definition at line 24 of file GaussJordan.cpp. Referenced by Invert().
