Operations
The concept SvdTraits has a linear solver using a singular value decomposition algorithm.

solve()

FT SvdTraits::solve	(	const Matrix &	M,
		Vector &	B
	)

Solves the system \( MX=B\) (in the least square sense if \( M\) is not square) using a singular value decomposition and returns the condition number of \( M\).

The solution is stored in \( B\).
