Need help.... How to plot sequences
显示 更早的评论
Hello,
I have a report due in two days and have no idea how to plot this sequence. I know almost nothing about Matlab and my tutors as usual have been no help at all.
If some one can help me out here I would greatly appriciate it.
The sequence is:
𝑥(𝑛) = {… , 5, 4, 3, 2, 1, 5, 4, 3, 2, 1, 5, 4, 3, 2, 1, … }
Cheers

Where does the n come into play? What do you want to plot when n = 10 for example?

Example —
x = 0:30;
y = mod(x, 15);
figure
plot(x, y)
grid
I leave the rest to you!

Use the colon operator with the ‘n’ vector, and then operate on it to create the triangular pulses.
That will eliminate the vector length problem.

Please experiment!
Use my example as a guide, and carefully read the documentation for colon. Note how to use it to code a descending sequence.
