class SymTMatrix

Detailed Description

This is the matrix space for a SymTMatrix with fixed sparsity structure.

The sparsity structure is stored here in the matrix space.

Constructor & Destructor Documentation

Ipopt::SymTMatrixSpace::SymTMatrixSpace ( Index  dim,
Index  nonZeros,
const Index iRows,
const Index jCols 
)

Constructor, given the number of rows and columns (both as dim), as well as the number of nonzeros and the position of the nonzero elements.

Note that the counting of the nonzeros starts a 1, i.e., iRows[i]==1 and jCols[i]==1 refers to the first element in the first row. This is in accordance with the HSL data structure. Off-diagonal elements are stored only once.

Ipopt::SymTMatrixSpace::~SymTMatrixSpace ( )

Destructor.
