function [sys, x0, str, ts] = arraysin(t, x, u, flag, num) 
%ARRAYSIN outputs function sin for a given vector input. 
%   This M-file is designed to be used in a SIMULINK S-function block. 
%   This function inputs NUM-array of input signal and outputs the 
%   sin function of the same array size signal.
