Function Documentation

PyObject* pyTupleList_FromDoubleArray	(	const double *	values,
		PyObject *	pList
	)

Convert a double array to a Python tuple list.

The list is (Python object, value) tuples

Returns Python tuple list with length = pList length

PyObject* pyTupleList_FromNode	(	DecompAlgo *	algo,
		DecompStatus	decompStatus
	)

Package a AlpsDecompTreeNode using a DecompAlgo into a Python list.

The list is (Python object, value) tuples

Returns Python tuple list

void pyColDict_AsPairedVector	(	PyObject *	pColDict,
		vector< pair< int, double > > &	vector,
		map< PyObject *, int >	indices
	)

Convert a column dictionary to a (int, double) vector.

The dictionary has columns as keys and coefficients as values

int pyColDict_AsPackedArrays	(	PyObject *	pColDict,
		map< PyObject *, int >	indices,
		int **	inds,
		double **	vals
	)

Convert a column dictionary to packed arrays.

The dictionary has columns as keys and coefficients as values

Returns length of index and value arrays

int pyColDict_AsPackedArrays	(	PyObject *	pColDict,
		map< PyObject *, int >	indices,
		int **	inds,
		double **	vals,
		DecompVarType &	varType
	)

CoinPackedMatrix* pyConstraints_AsPackedMatrix	(	PyObject *	pRowList,
		map< PyObject *, int >	rowIndices,
		map< PyObject *, int >	colIndices
	)

Convert a list of Python constraints to a CoinPackedMatrix.

The format of each constraint is as a dictionary with variables as keys and coefficients as values

void addTupleToPyList	(	PyObject *	pList,
		PyObject *	key,
		PyObject *	value
	)

Creates a (key,value) tuple and appends to a Python list of tuples *.

void insertTupleToPyList	(	PyObject *	pList,
		unsigned	position,
		PyObject *	key,
		PyObject *	value
	)

Creates a (key,value) tuple and inserts in a Python list of tuples *.
