Detailed Description

Class to store the compressed symmetric matrix of a hessian row.

Member Function Documentation

Push()

void INMOST::Sparse::HessianRow::Push ( index  ind, INMOST_DATA_REAL_TYPE  val  )

inline

Push specified element into sparse row.

This function should be used only if the index is not repeated in the row.

Definition at line 426 of file inmost_sparse.h.

Resize()

void INMOST::Sparse::HessianRow::Resize ( INMOST_DATA_ENUM_TYPE  size )

inline

Resize row to specified size.

It is intended to be used together with non-const Row::GetIndex and Row::GetValue that allow for the modification of individual entries.

Parameters

size	New size of the row.
