How to clear this Error :In an assignment A(I) = B, the number of elements in B and I must be the same

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.

I dont see the attachment error file! Where the t and x are used in the mdlOutputs?

[Image Analyst]

How are you calling mdlOutputs()? What are you passing in for t, x, and u?

[Charanraj]

this is the error i get. I am not passing anything for t , x. I am just passing only the values of u. For this it just shows warning !

[Kaustubha Govind]

I'd recommend setting a breakpoint in the mdlOutputs function and stepping through it to find the cause of the error.

Can anyone help me how to create break point ?

hey all, finally solved the error. I did not initialize the values in a separate .m file. That was the fault i did..

thanks...
