h_norm - H-infinity norm

Calling Sequence

[hinfnorm [,frequency]]=h_norm(sl [,rerr])

Parameters

• sl : the state space system ( syslin list)
• rerr : max. relative error, default value 1e-8
• hinfnorm : the infinity norm of Sl
• frequency : frequency at which maximum is achieved

Description

produces the infinity norm of a state-space system (the maximum over all frequencies of the maximum singular value).
