Need help with Plotting inside a time loop please!

t = [0:100]; wavomega=0.5; f=100; if t>10 && t<15 Ft = f*sin(wavomega*t); else Ft =0; end figure; plot(Ft,t)

This gives an error and says t is not a scalar?? Please help how to plot this.? Is it because Ft is changing in every loop?

Please help.

Instead of the if, use directly

Ft=zeros(1,length(t))
Ft = f*sin(wavomega*t(11:14))

Thank John,

ITs not working. Says * matrix dimensions must match

Vignesh

this works:

t = [0:100]; 
wavomega=0.5; 
f=100;
Ft=zeros(1,length(t))
Ft([11:14]) = f*sin(wavomega*t([11:14])); 
stem(t,Ft)

is this ok? regards

John
