Functions
std::pair< Matrix< NumberS >, DiagonalMatrix< NumberS > >	myra::stev (const CVectorRange< NumberS > &T0, const CVectorRange< NumberS > &T1)
	Eigendecomposes a real symmetric tridiagonal T into X*D*X', where X'*X = X*X' = I and D is diagonal.
std::pair< Matrix< NumberD >, DiagonalMatrix< NumberD > >	myra::stev (const CVectorRange< NumberD > &T0, const CVectorRange< NumberD > &T1)
	Eigendecomposes a real symmetric tridiagonal T into X*D*X', where X'*X = X*X' = I and D is diagonal.
void	myra::stev_inplace (const MatrixRange< NumberS > &X, const VectorRange< NumberS > &T0, const VectorRange< NumberS > &T1)
	Eigendecomposes a real symmetric tridiagonal T into X*D*X', where X'*X = X*X' = I and D is diagonal.
void	myra::stev_inplace (const MatrixRange< NumberD > &X, const VectorRange< NumberD > &T0, const VectorRange< NumberD > &T1)
