Detailed Description

template<class T>
class TNT::Sparse_Matrix_CompRow< T >

Read-only view of a sparse matrix in compressed-row storage format. Neither array elements (nonzeros) nor sparsity structure can be modified. If modifications are required, create a new view.

Index values begin at 0.

Storage requirements: An (m x n) matrix with nz nonzeros requires no more than ((T+I)*nz + M*I) bytes, where T is the size of data elements and I is the size of integers.

TNT::Sparse_Matrix_CompRow< T >::Sparse_Matrix_CompRow	(	int	M,
		int	N,
		int	nz,
		const T *	val,
		const int *	r,
		const int *	c
	)

Construct a read-only view of existing sparse matrix in compressed-row storage format.

Parameters:

M	the number of rows of sparse matrix
N	the number of columns of sparse matrix
nz	the number of nonzeros
val	a contiguous list of nonzero values
r	row-pointers: r[i] denotes the begining position of row i (i.e. the ith row begins at val[row[i]]).
c	column-indices: c[i] denotes the column location of val[i]
