gamitg

gamitg — H-infinity gamma iterations

Calling sequence

[gopt]=gamitg(G,r,prec [,options]);

`G`	: `syslin` list (plant realization )
`r`	: 1x2 row vector (dimension of `G22`)
`prec`	: desired relative accuracy on the norm
`option`	: string `'t'`
`gopt`	: real scalar, optimal H-infinity gain

gopt=gamitg(G,r,prec [,options]) returns the H-infinity optimal gain gopt.

G contains the state-space matrices [A,B,C,D] of the plant with the usual partitions:



   B = ( B1 , B2 ) ,    C = ( C1 ) ,    D = ( D11  D12)
                            ( C2 )          ( D21  D22)

These partitions are implicitly given in r: r(1) and r(2) are the dimensions of D22 (rows x columns)

With option='t', gamitg traces each bisection step, i.e., displays the lower and upper bounds and the current test point.
