. We want to solve an optimization problem with constraints in the form of bilinear matrix inequalities. The problem is stored
            in a file <tt>bmidata.mat</tt> in directory <tt>interfaces/BMI</tt>. The structure of the datafile is explained in Appendix BMI. All the user has to do to solve the problem is to call the following
            sequence of commands:
         </p><pre>load bmidata
penm=bmi_define(bmidata);
prob=penlab(penm);
prob.solve();</pre><p><b>Polynomial matrix inequalities</b></p>
