Index exceeds matrix dimensions when doing simulation

Hi all,

I am a fresh Matlab user and I am running the following codes.I want to simulate the data with different functions according to different States,but I have the problem of Index exceeds matrix dimensions. Please let me know how I should solve this problem.

Thank you so much! Edwin

 for j=2:nr;
    if States(j,1)==1;
       yvar(j,2:9)=yvar(j-1,:)*Coeff.S_Param{1,1}+rr{1,1}(j,:);
    end
    if States(j,2)==1;
       yvar(j,2:9)=yvar(j-1,:)*Coeff.S_Param{1,2}+rr{1,2}(j,:);
    end
    if States(j,3)==1;
       yvar(j,2:9)=yvar(j-1,:)*Coeff.S_Param{1,3}+rr{1,3}(j,:);
    end
    if States(j,4)==1;
       yvar(j,2:9)=yvar(j-1,:)*Coeff.S_Param{1,2}+rr{1,4}(j,:);
    end
  end

Check the sizes of your variables, and don't exceed these dimensions. For example if your matrix A is 4x3, you can't write A(5,1)

Thank you.

I found another mistake according to what you said.

Cheers, Edwin
