Detailed Description

template<class T> class TNT::Sparse_Matrix_CompRow

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.

Constructor & Destructor Documentation

template<class T>
TNT::Sparse_Matrix_CompRow<T>::Sparse_Matrix_CompRow<T> ( const Sparse_Matrix_CompRow<T> & S )

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

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]
