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 ( 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
int searchLowerIndex ( int  key) const [inline]
Returns:
the largest k such that for all j in [0,k) index[j]<key
