LUDecomposition::~LUDecomposition
~LUDecomposition()
This is the default LUDecomposition destructor.
Definition: ludecomposition.h:24

LUDecomposition::Solve
DoubleVector Solve(const DoubleVector &b)
This function will solve the matrix equation A = bx and return the resulting DoubleVector.
Definition: ludecomposition.cc:50

LUDecomposition::LUDecomposition
LUDecomposition()
This is the default LUDecomposition constructor.
Definition: ludecomposition.h:15

LUDecomposition::getLogDet
double getLogDet()
This function will return the log of the determinate of the matrix.
Definition: ludecomposition.h:35

LUDecomposition::isIllegal
int isIllegal()
This function will return the flag to denote whether the algorithm will fail.
