A type used to hold the components of a sparse matrix in compressed sparse row (CSR) format.

Field Documentation

template<class FPType>

std::vector<uint32_t> nag::csr_mat< FPType >::col_indx

col_indx is a vector of length nnz. col_indx[i] gives the column index of the ith non-zero element.

template<class FPType>

size_t nag::csr_mat< FPType >::m

m is the number of rows of the matrix.

template<class FPType>

size_t nag::csr_mat< FPType >::n

n is the number of columns of the matrix.

template<class FPType>

size_t nag::csr_mat< FPType >::nnz

nnz is the number of non-zero elements.

template<class FPType>

std::vector<size_t> nag::csr_mat< FPType >::row_ptr

row_ptr is a vector of length m + 1. row_ptr[i] gives the start of row i in the col_indx and values vectors (the final element should be equal to nnz).

template<class FPType>

std::vector<FPType> nag::csr_mat< FPType >::values

values is a vector of length nnz. values[i] gives the value of the ith non-zero element.
