    function [r, x, y] = pctdemo_task_radar(numSims, finishTime)
%PCTDEMO_TASK_RADAR Perform radar simulation for the Parallel Computing
%Toolbox Radar example.
%   Runs the Simulink model pctdemo_model_radar.  Returns the error in the 
%   estimated aircraft location (i.e. the residual) and the x and the y 
%   coordinates of the aircraft location.
%   The matrices returned are of the size (finishTime+1)-by-numSims.
