Detailed Description

template<class T>
class TNT::Sparse_Matrix< 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+2I)*nz) bytes, where T is the size of data elements and I is the size of integer subscripts.

The documentation for this class was generated from the following file:
