Subtracts matrices and assign.

Perform subtraction between matrices and assigns the result to matrix.

Perform standard linear algebra subtraction. Matrices must have the same CoefficientType but can have different ChainTypeFlag. The addition is optimized for each combination of ChainTypeFlag.

Parameters

matrix	The first matrix.
other	The second matrix.

Returns

A reference to the modified matrix matrix containing the result.

Functions
Sparse_matrix &	CGAL::OSM::Sparse_matrix< CoefficientType, ChainTypeFlag >::operator-= (const Sparse_matrix &other)
	Matrices subtraction and assign: COLUMN -= COLUMN or ROW -= ROW.
