nengolib.signal.Hankel

class nengolib.signal.Hankel

Scaled realization given by the Hankel singular values.

This (generously) bounds the worst-case state vector by the given radii. Thus, the radii that are given should be much smaller than the actual desired radius in order to compensate.

The worst-case output is given by the l1_norm() of a system which in turn is bounded by 2 times the sum of the Hankel singular values. [1]
