List of all members.

Public Methods
constructors and destructor
	MdataC ()
	default constructor is explicit and creates an empty valarray.
	MdataC (const int nr, const int nc, const Tp value)
	standard constructor needs at least number of rows and optionally number of columns.
	MdataC (const int nr, const int nc, const int nu, const Tp value)
	constructor to be called for general banded matrix.
	MdataC (const Tp* a, const int nr, const int nc)
	constructor from a C style array.
	MdataC (const valarray<Tp>& a, const int nr, const int nc)
	constructor from a valarray.
	~MdataC ()
	destructor.
miscellaneous helper methods
MdataC*	get_own_copy ()
	this method is called to instantiate a unique copy of the matrix data.
void	assign (const Tp value)
	assign data array with a constant value.
void	assign (const int nr, const Tp* value)
	assign with a C-style double array.
void	assign (const int nr, const int nc, const Tp** value)
	assign with the old LinAl C-style Matrix.
void	resize (const int nr, const int nc)
	resize the data space allocated w/o loosing any data.
Public Attributes
MdataC actual data
valarray<Tp>	m
	matrix coefficients are stored in an STL valarray.
int	nrow
	number of rows.
int	ncol
	number of columns.
int	nref
	number of references to the data.
int	ku
	the number of superdiagonals (if a banded matrix).
int	kl
	the number of subdiagonals, kl=nr-ku-1; (if a banded matrix).

Detailed Description

template<class Tp> template class MdataC

Column oriented storage of Matrix data
