Member Function Documentation

◆ coeff()

template<typename Derived >
Scalar Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::coeff ( Index  row,
Index  col 
) const
inline

Returns
the value of the matrix at position i, j This function returns Scalar(0) if the element is an explicit zero

◆ cols()

template<typename Derived >
Index Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::cols ( void  ) const
inline

Returns
the number of columns.
See also
rows()

◆ innerIndexPtr()

template<typename Derived >
const StorageIndex* Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::innerIndexPtr ( ) const
inline

Returns
a const pointer to the array of inner indices. This function is aimed at interoperability with other libraries.
See also
valuePtr(), outerIndexPtr()

◆ innerNonZeroPtr()

template<typename Derived >
const StorageIndex* Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::innerNonZeroPtr ( ) const
inline

Returns
a const pointer to the array of the number of non zeros of the inner vectors. This function is aimed at interoperability with other libraries.
Warning
it returns the null pointer 0 in compressed mode

◆ innerSize()

template<typename Derived >
Index Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::innerSize ( ) const
inline

Returns
the size of the inner dimension according to the storage order, i.e., the number of rows for a columns major matrix, and the number of cols otherwise

◆ isCompressed()

template<typename Derived >
bool Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::isCompressed ( ) const
inline

Returns
whether *this is in compressed form.

◆ nonZeros()

template<typename Derived >
Index Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::nonZeros ( ) const
inline

Returns
the number of non zero coefficients

◆ outerIndexPtr()

template<typename Derived >
const StorageIndex* Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::outerIndexPtr ( ) const
inline

Returns
a const pointer to the array of the starting positions of the inner vectors. This function is aimed at interoperability with other libraries.
See also
valuePtr(), innerIndexPtr()

◆ outerSize()

template<typename Derived >
Index Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::outerSize ( ) const
inline

Returns
the size of the storage major dimension, i.e., the number of columns for a columns major matrix, and the number of rows otherwise

◆ rows()

template<typename Derived >
Index Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::rows ( void  ) const
inline

Returns
the number of rows.
See also
cols()

◆ valuePtr()

template<typename Derived >
const Scalar* Eigen::SparseMapBase< Derived, ReadOnlyAccessors >::valuePtr ( ) const
inline

Returns
a const pointer to the array of values. This function is aimed at interoperability with other libraries.
