		unsigned int *	reference,
		double *	weights,
		double	scaleFactor
	)

Updates two arrays for steepest.

AbcMatrix3& AbcMatrix3::operator=

(

const AbcMatrix3 &

)

void AbcMatrix3::sortBlocks

(

const AbcSimplex *

model

)

Sort blocks.

void AbcMatrix3::swapOne	(	const AbcSimplex *	model,
		const AbcMatrix *	matrix,
		int	iColumn
	)

Swap one variable.
