I personally inform that i still beginner in Comsol Script. I wanted to learn about the comsol, how to simulate the graph. I tried plot(x,y). but i need to use this function simulate(Ss1,(U1,U2)). But at the end, it show Syntax error.(adsbygoogle = window.adsbygoogle || []).push({});

Heres the details of the code:

Ks = 600000; %spring stiffness of the car

M = 1200; %mass of the car

KST = 15000000; % New value for spring stiffness

MH = 48; % Constant value of the car.

A = [0 1 0 0 ; (-Ks+KST)/MH -Kv/MH -Ks/MH Kv/MH; 0 0 0 1; Ks/M Kv/M -Ks/M -Kv/M];

B= [0 0; KST/MH -1/MH; 0 0; 0 1/M];

C = [1 0 0 0; 0 0 1 0; 0 1 0 0; 0 0 0 1];

D = [0 0; 0 0; 0 0; 0 0];

Ss1 = ss(A, B, C, D);

T = [0:0.01:10]';

S1 = zeros(size(T));

S2 = 3000*ones(size(T));

U1 = sig(S1, T);

U2 = sig(S2, T);

simulate(Ss1,(U1, U2))

From the beginning, i type all the code together. can when it comes to U1=sig(S1,T);

it shows Error: SIG constructor: Length of t must equal number of rows in y

sig.sig 96 error('SIG constructor: Length of t must equal number of rows in y')

until the end i couldn't get the graph. How can i get the graph done? how to modify the sig code? i have no idea. i tried many times already. those who know. plz take a look. Help me plz. Thx in advance
