Hi there,
I want to plot u1 vs t but it is showing me error. How can i plot this?
syms q1(t)
q1=cos(D1*t)*qu0(1,1);
syms q2(t)
q2=cos(D2*t)*qu0(2,1);
syms q3(t)
q3=cos(D3*t)*qu0(3,1);
syms q4(t)
q4=cos(D4*t)*qu0(4,1);
syms q5(t)
q5=cos(D5*t)*qu0(5,1);
u1=V(1,1)*q1+V(1,2)*q2+V(1,3)*q3+V(1,4)*q4+V(1,5)*q5
where D1, D2, D3, D4, D5 are constants, and qu0(1,1) is first entry of vector qu0.
q1,q2,q3,q4,q5 are equations in terms of variable t.
V(1,1), V(1,2), V(1,3), V(1,4), V(1,5) are vectors from a matrix V.

q1(t) = cos(D1*t)*qu0(1,1);
q2(t) = cos(D2*t)*qu0(2,1);
q3(t) = cos(D3*t)*qu0(3,1);
q4(t) = cos(D4*t)*qu0(4,1);
q5(t) = cos(D5*t)*qu0(5,1);
u1(t) = V(1,1)*q1(t) + V(1,2)*q2(t) + V(1,3)*q3(t) + V(1,4)*q4(t) + V(1,5)*q5(t);
fplot(u1, [-5 5]) %-5 5 are the start and end times
