I'm getting this error "Error using vertcat The following error occurred converting from double to function_handle: Too many output arguments"
here's my code
m1=55;
m2=400;
m3=100;
k1=230000;
k2=30000;
k3=50000;
k4=3000;
n2=1500;
n3=4000;
n4=700;
ti=0;
tf=20;
tm=(ti+tf)/2;
t1=tf/4;
L0=5;
v=15;
A=0.03;
M=[0 1 0 0 0 0;
-(k1+k2)/m1 -(n2+n4)/m1 k2/m1 n4/m1 0 n4/m1;
0 0 0 1 0 0;
k2/m2 n2/m2 -(k3+k2)/m2 -(n3+n2)/m2 k3/m2 n3/m2;
0 0 0 0 0 1;
k4/m3 n4/m3 k3/m3 n3/m3 -(k3+k4)/m3 -(n3+n4)/m3];
fM= @(t,y) M*y+vect;
%Scenario 1
u1 = @(t) (A/2)*[1-cos(2*pi*v*t/L0)]
vect=[0;u1;0;0;0;0];
[T, Y1] = ode45(fM,[ti,tf],vect)
I'm going to say upfront that I'm not totally sure if this code even makes sense so any help would be appreciated

As u1 is a function handle it needs t as input...you input t into it and then call the line you wanted.
t = 0:0.001:1 ;
vect=[0;u1(t)';0;0;0;0];
