virtual bool Ipopt::Ma28TDependencyDetector::InitializeImpl	(	const OptionsList &	options,

Has to be called to initialize and reset these objects.

Implements Ipopt::TDependencyDetector.

		Index	n_cols,
		Index	n_jac_nz,

	)			`[virtual]`

Method determining the number of linearly dependent rows in the matrix and the indices of those rows.

We assume that the matrix is available in "Triplet" format (MA28 format), and that the arrays given to this method can be modified internally, i.e., they are not used by the calling program anymore after this call. This method returns false if there was a problem with the underlying linear solver.

Implements Ipopt::TDependencyDetector.
