You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: Solver_mixedpoleMIMO.m
    path of file: ./repos/lc_toolbox/Modules/Control/Solvers
    
    the code of the file until where you have to start completion: classdef Solver_mixedpoleMIMO < Solver
    methods
        function self = Solver_mixedpoleMIMO(options)
            disp('Solving with mixedpoleMIMO, because there is a closed loop pole regions constraint added.')
            
            if nargin > 0
                self = setoptions(self,options);
            end
        end
        
        function self = solve(self,config,specs,vars)
            % Compute plant state-space
            specs = rescale(specs,'constr+bound');
            [P,~,~,ch] = Solver.plant(config,specs,vars);
          
            % Weights for the norms in the objective
            alpha = zeros(1,length(specs.performance));
