I am writting codes to a s-function block to create demo or animate of a liquid Tank ,but I have a problem which is "not enough Arguments".I am not sure if you know what is the problem,I have paste my written codes below.
function [sys,x0,str,ts,setPt1,setPt2,waterx1,vessel1Hndl,vessel1Ht, vesselHndlList,waterY1,vessel2Hndl,lineHndl1,lineHndl2]=vesseldemo2project (u,flag,t,x)
switch flag==4
case 0
[sys,x0,str,ts,vesseldemo2project]=mdlInitializeSizes;
get(vesseldemo2project,'UserData') =vesselHndlList;
get( vesselHndlList(1),'YData');
yData(1)=yOffset;
yData(3:4)=[1 1]*u(2)+yOffset;
set( vesselHndlList(1),'YData',yData);
yData=get(x(2),'YData');
yData([3 4])=[1 1]*u(2)+yOffset;
set(x(2),'YData',yData);
yData=[1 1]*u(1)+1;
set(x(3),'YData',yData);
case 2
%Tank body details.................................
sys=mdlUpdate(t,x,u);
vessel1Ht=1;

vessel1Init=0;
setPt1=0.5;
setPt2=0.75;
vesselx=[0 0 1 1]-0.5;
vesselY=[1 0 0 1];
line(1.1*vesselx*vessel1Wid+1,vesselY*vessel1Ht+0.95,'LineWidth',2,'Color','black');
% Draw the water..............................................
waterx1=vesselx*vessel1Wid+1;
waterx=vesselY*vessel1Init+1;
x=patch(waterx,waterx,'blue','EdgeColor','none');
% Draw the gray wall............................................
