Detailed Description

template<class T>
class SimpleMatrix< T >

A simple matrix class.

This class defines a matrix built by STL vectors. It is basically a variable-dimension vector of vectors; the dimension is defined at construction and cannot be changed in current implementation. It is intended as a container and not for algebraic manipulations. The class provides a standard access operator [].

Constructor & Destructor Documentation

template<class T>

SimpleMatrix< T >::SimpleMatrix	(	unsigned int	nRows,
		unsigned int	nCols,
		T	elements = T()
	)			[inline]

Constructor.

The constructor will build an nRows x nCols matrix, initialized with a default value. If T is a class with no default constructor, a default value for T must be provided, which will be replicated in every matrix element.

Parameters:

	nRows	The number of rows.
	nCols	The number of columns
	elements	The initialization value for the matrix elements.
