In the below hexagon figure, the parallelogram of coordinate (g,h) is the base plane on which I am working on.

In this plane (g,h) is the reference plane & input of the coding. By this simple logic, if reference coordinates is fed in to the system, all the four coordinates will be found/calculated & that is the idea of the s function code. For an example: If (g,h) is (1.15,0.69) then the four coordinate points

    (m1,n1)=(1,0)
    (m2,n1)=(2,0)
    (m1,n2)=(1,1)
    (m2,n2)=(2,2)

will be found & that's the idea.

Attached is a picture of the error, model file & parallelogram inside hexagon.

Guidance/help to eradicate this problem are most welcome.

My S function program:

function sys = mdlOutputs(t,x,u)  
  g=u(1);  
  h=u(2);  
  global m;  
  global n;  
  global m1;  
  global m2;  
  global n1;  
  global n2;  
  m=0;
  while (g<m)
    m1=(m-1);
    m2=m;
   if (g>m)
    m=m+1;
   end
  end
  n=0;
  while (h<n)
     n1=(n-1);
     n2=n;
   if (h>n)
     n=n+1;
   end
  end
  M1=m1;  
  M2=m2;  
  N1=n1;  
  N2=n2;  
  sal(1)=M1;  
  sal(2)=M2;  
  sal(3)=N1;  
  sal(4)=N2;  
  sys=sal;
% End of mdlOutputs.
