csr_to_dense_matrix()

template<typename T >

Eigen::Matrix< value_type_t< T >, Eigen::Dynamic, Eigen::Dynamic > stan::math::csr_to_dense_matrix ( int  m, int  n, const T &  w, const std::vector< int > &  v, const std::vector< int > &  u  )

inline

Construct a dense Eigen matrix from the CSR format components.

Template Parameters

T	type of the matrix

Parameters

[in]	m	Number of matrix rows.
[in]	n	Number of matrix columns.
[in]	w	Values of non-zero matrix entries.
[in]	v	Column index for each value in w.
[in]	u	Index of where each row starts in w.

Returns

Dense matrix defined by previous arguments.

Exceptions

std::domain_error	If the arguments do not define a matrix.
std::invalid_argument	if m/n/w/v/u are not internally consistent, as defined by the indexing scheme. Extractors are defined in Stan which guarantee a consistent set of m/n/w/v/u for a given sparse matrix.
std::out_of_range	if any of the indices are out of range.
