gamitg(5)

NAME
gamitg - H-infinity gamma iterations

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

PARAMETERS

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

DESCRIPTION
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 implicitely 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.
