Hi All,
I have an assignment to modify code given by a book. But, somehow the code contain "Error using horzcat Dimensions of arrays being concatenated are not consistent". I have tried to browse, what could be the problem, but still not get the solution. Kindly help the code below.
The error lies in X1(i,:)=[Y' dY' t];
F1=1;
F2=-1;
M1=1;
M2=1.5;
B=0.1;
K=0.2;
Coef_1=[B/M1 -B/M1 -B/M2 B/M2];
Coef_2=[K/M1 -K/M1 -K/M2 K/M2];
Y=[0.1; 0.1];
dY=[0; 0];
dt=0.1;
t=0;
tsim=200;
n=round(tsim-t)/dt;
for i=1:n
X1(i,:)=[Y' dY' t];
ddY=[F1/M1;F2/M2] - Coef_1.*dY - Coef_2.*Y;
dY=dY+dt.*ddY;
Y=Y+dt.*dY;
t=t+dt;
end
figure(1)
plot(X(:,5),X(:,1:2))
xlabel('Time (sec.)')
ylabel('Displacements')
figure(2)
plot(X(:,5),X(:,3:4))
xlabel('Time (sec.)')
ylabel('Velocities')
