Hi, I am trying to input a signal which is a sine wave between 3 and 7 seconds and zero everywhere else. I am trying to create an 'for loop' to do this by indexing the time vector but I can't make it work, the graph just displays nothing (assuming matlab thinks x = 0 for all time?)…is there anything I've missed?
t = [0:0.1:10];for k=1:length(t)if t(k)>=3 && t(k)<=7x = 5*sin(4*pi *t);elsex = 0;endendplot(t,x)
Any help would be greatly appreciated 🙂
