Public Member Functions
	PivotMatrix ()
	Default constructor, makes size 0x0 empty PivotMatrix.

	PivotMatrix (int in_N)
	Initializes to identity matrix of size N.

	PivotMatrix (const PivotMatrix< Number > &that)
	Copy constructor.

void	swap (PivotMatrix< Number > &that)
	Member swap.

PivotMatrix< Number > &	operator= (PivotMatrix that)
	Copy-assignment operator.

	PivotMatrix (InputStream &in)
	InputStream constructor, complements write(OutputStream) method.

void	write (OutputStream &out) const
	Writes to OutputStream, complements InputStream constructor.

Matrix22< Number > &	operator[] (int n)
	Inserts new 2x2 block at offset n.

void	push_back (const PivotMatrix< Number > &that)
	Enlarges *this PivotMatrix by appending that one.

void	conjugate ()
	Applies conjugate to *this.

void	transpose ()
	Applies transpose to *this.

void	hermitian ()
	Applies hermitian transpose to *this.

void	reverse ()
	Applies reverse operation to this (fliplr then flipud).

void	solve (const Range &B, char side, char op) const
	Solves op(A)X=B or Xop(A)=B, overwrites B with X.

void	multiply (const Range &B, char side, char op) const
	Multiplies op(A)B=X or Bop(A)=X, overwrites B with X.

Matrix< Number >	make_Matrix () const
	Returns equivalent Matrix.
