LMITOOL is built around the Scilab function lmisolver. This
function computes the solution 
of
problem 
, given functions f, 
and 
. To solve
, user must provide an evaluation function which
``evaluates'' f, and as a function the unknown matrices,
as well as an initial guess on the values of the unknown matrices. User can either
invoke lmisolver directly, by providing the necessary information in a
special format or he can use the interactive
function lmitool described in Section 3.
