Functions
LUResult	MathLin::LU (const math_Matrix &theA, double theMinPivot=1.0e-20)
	Perform LU decomposition of matrix A with partial pivoting. Decomposes A into L*U where L is lower triangular with unit diagonal and U is upper triangular. The result stores L and U in a combined matrix.
LinearResult	MathLin::Solve (const math_Matrix &theA, const math_Vector &theB, double theMinPivot=1.0e-20)
	Solve linear system AX = B using LU decomposition.
LinearMultipleResult	MathLin::SolveMultiple (const math_Matrix &theA, const math_Matrix &theB, double theMinPivot=1.0e-20)
	Solve multiple linear systems AX = B where B is a matrix. Each column of B is a separate right-hand side.
LinearResult	MathLin::Determinant (const math_Matrix &theA, double theMinPivot=1.0e-20)
	Compute determinant of matrix A.
InverseResult	MathLin::Invert (const math_Matrix &theA, double theMinPivot=1.0e-20)
	Compute inverse of matrix A.
