Given values of decision variables, derive corresponding values of matrix variables


valX = dec2mat(lmisys,decvars,X)


Given a value decvars of the vector of decision variables, dec2mat computes the corresponding value valX of the matrix variable with identifier X. This identifier is returned by lmivar when declaring the matrix variable.

Recall that the decision variables are all free scalar variables in the LMI problem and correspond to the free entries of the matrix variables X1, . . ., XK. Since LMI solvers return a feasible or optimal value of the vector of decision variables, dec2mat is useful to derive the corresponding feasible or optimal values of the matrix variables.
