Constructor & Destructor Documentation

◆ Map() [1/2]

template<typename SparseMatrixType>
Eigen::Map< SparseMatrixType >::Map ( Index rows,
Index cols,
Index nnz,
StorageIndex * outerIndexPtr,
StorageIndex * innerIndexPtr,
Scalar * valuePtr,
StorageIndex * innerNonZerosPtr = 0 )
inline

Constructs a read-write Map to a sparse matrix of size rows x cols, containing nnz non-zero coefficients, stored as a sparse format as defined by the pointers outerIndexPtr, innerIndexPtr, and valuePtr. If the optional parameter innerNonZerosPtr is the null pointer, then a standard compressed format is assumed. The inner indices must be sorted appropriately.

This constructor is available only if SparseMatrixType is non-const.

More details on the expected storage schemes are given in the manual pages.

◆ Map() [2/2]

template<typename SparseMatrixType>
Eigen::Map< SparseMatrixType >::Map ( Index rows,
Index cols,
Index nnz,
const StorageIndex * outerIndexPtr,
const StorageIndex * innerIndexPtr,
const Scalar * valuePtr,
const StorageIndex * innerNonZerosPtr = 0 )
inline

This is the const version of the above constructor.

This constructor is available only if SparseMatrixType is const, e.g.:

Map(Index rows, Index cols, Index nnz, StorageIndex *outerIndexPtr, StorageIndex *innerIndexPtr, Scalar *valuePtr, StorageIndex *innerNonZerosPtr=0)
Definition SparseMap.h:237
