Public Member Functions

Destructor
virtual ~HepGenMatrix()
()
virtual HepDouble & operator()(int row, int col) = 0
virtual const HepDouble & operator()(int row, int col) const = 0
Read or write a matrix element.
** Note that the indexing starts from (1,1) **
[]
inline HepGenMatrix_row operator[] (int)
inline const HepGenMatrix_row_const operator[] (int) const
Read or write a matrix element.
While it may not look like it, you simply do m[i][j] to get an element.
** Note that the indexing starts from [0][0] **
error
static void error(const char *s)
invert
virtual void invert(int&) = 0
num_col
virtual int num_col() const = 0
num_row
virtual int num_row() const = 0
swap
inline static void swap(int&, int&)
inline static void swap(HepDouble *&, HepDouble *&)

Non-Member Functions

norm
HepDouble norm(const HepGenMatrix &m)
2-norm of a matrix.
norm1
HepDouble norm1(const HepGenMatrix &m)
1-norm of a matrix.
norm_infinity
HepDouble norm_infinity(const HepGenMatrix &m)
Infinity-norm of a matrix.
