Classes
class	myra::Action< Number >
	Applies the "Action" of a linear operator, b := A*x. More...
class	myra::VectorRange< Number >
	Represents a mutable VectorRange. More...
class	myra::MatrixRange< Number >
	Represents a mutable MatrixRange. More...
class	myra::DiagonalMatrix< Number >
	Tabulates the values of a square NxN diagonal matrix. Allows random access, but only on the diagonal. More...

Functions
float	myra::power (const Action< float > &A, const VectorRange< float > &x, float tolerance=1.0e-4f, int iterations=100)
	Applies the power method to compute the dominant eigenpair from an initial guess x. Results lambda, overwrites x.
double	myra::power (const Action< double > &A, const VectorRange< double > &x, double tolerance, int iterations)
DiagonalMatrix< float >	myra::power (const Action< float > &A, const MatrixRange< float > &X, float tolerance=1.0e-4f, int iterations=100)
	Applies orthogonal iteration to compute dominant eigenpairs from an initial guess X. Returns lambda, overwrites X.
