MATLAB: Need help…. How to plot sequences

MATLAB and Simulink Student Suitesequence

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:

?(?) = {… , 5, 4, 3, 2, 1, 5, 4, 3, 2, 1, 5, 4, 3, 2, 1, … }

Cheers

The mod function and the colon,: operator are your friends!

MATLAB: How to plot a sequence over a given interval

In the code mentioned above the length of vector 'n' is 33, the length of vector 'x' is 75, Hence the plot function is giving error.

Use the following code:

n = linspace(-20,12,75);
x = repmat([5,4,3,2,1],3 ,15);
plot(n,x)
xlim([-20 12])

The aboce code should give the saw-tooth output.
