Detailed Description

template<typename Scalar>
class Eigen::CompressedStorage< Scalar >

Stores a sparse set of values as a list of values and a list of indices.

Member Function Documentation

Scalar at	(	int	key,
		Scalar	defaultValue = Scalar(0)
	)		const [inline]

Returns:

the stored value at index key If the value does not exist, then the value defaultValue is returned without any insertion.

Scalar atInRange	(	std::size_t	start,
		std::size_t	end,
		int	key,
		Scalar	defaultValue = Scalar(0)
	)		const [inline]

Like at(), but the search is performed in the range [start,end)

Scalar& atWithInsertion	(	int	key,
		Scalar	defaultValue = Scalar(0)
	)		[inline]

Returns:

a reference to the value at index key If the value does not exist, then the value defaultValue is inserted such that the keys are sorted.

int searchLowerIndex

(

int

key

)

const [inline]

Returns:

the largest k such that for all j in [0,k) index[j]<key

int searchLowerIndex	(	std::size_t	start,
		std::size_t	end,
		int	key
	)		const [inline]

Returns:

the largest k in [start,end) such that for all j in [start,k) index[j]<key
