lsim( SS, [2;0.2], t)
this is the code ss is a state space model with 2 inputs and t is 0:0.4:10

'u' must have as many rows as the number of elements in 't'. It seems that you want to apply step inputs. Try something like this
t = 0:0.4:10;
u = repmat([2, 0.2], numel(t), 1);
lsim(SS, u, t);

You need to specify it as two columns. The number of rows should be the same as the number of elements in t. u is like this
u = [
2 0.2;
2 0.2;
..
..
2 0.2]; % rows same as numel(t)
