% SIMLINQ2.M      (Model of Linear Quadratic Problem, s-function)
%
% This function implements the model of the Linear Quadratic Problem.
%
% Syntax:  [sys, x0] = simlinq2(t, x, u, flag)
%
% Input parameters:
%    t         - given time point
%    x         - current state vector
%    u         - input vector
%    flag      - flags
%
% Output parameters:
%    sys       - Vector containing the new state derivatives
%    x0        - initial value
