	Represents a mutable SparseMatrixRange. More...

Functions
DiagonalMatrix< NumberS >	myra::equilibrate (const SparseMatrixRange< NumberS > &A)
	Computes a DiagonalMatrix E such that each row/column of E*A*E has roughly equal norm. Returns E, overwrites A with E*A*E.
DiagonalMatrix< NumberD >	myra::equilibrate (const SparseMatrixRange< NumberD > &A)
	Computes a DiagonalMatrix E such that each row/column of E*A*E has roughly equal norm. Returns E, overwrites A with E*A*E.
DiagonalMatrix< NumberC >	myra::equilibrate (const SparseMatrixRange< NumberC > &A)
	Computes a DiagonalMatrix E such that each row/column of E*A*E has roughly equal norm. Returns E, overwrites A with E*A*E.
DiagonalMatrix< NumberZ >	myra::equilibrate (const SparseMatrixRange< NumberZ > &A)
	Computes a DiagonalMatrix E such that each row/column of E*A*E has roughly equal norm. Returns E, overwrites A with E*A*E.
