Index exceeds matrix dimensions.

Hi, i get the following error and didn't find a solution yet

MATLAB code
syms L1 L2 L3 L4 L5 L6 L7 L8 L9 L10 L11
X = [L1; L2; L3; L4; L5; L6; L7; L8; L9; L10; L11];
syms Xi
BGx = sym(zeros(6,1));
for i=1:1:6
  BGx(i,1)=L1*Xi(i)  
end

I want to get 6 terms like L1*Xi1, L1*Xi2 etc... Thanks for your help

[Andrei Bobrov]

L = sym('L',[1,11]);
Xi = sym('Xi',[1,6]);

BGx = L.'*Xi;

or in your case

BGx = sym('L1')*sym('Xi',[1,6]);
