create a graph with a specific interval

[Steven Lord]

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the MATLAB Onramp tutorial (https://www.mathworks.com/support/learn-with-matlab-tutorials.html) to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

n=0:35

x1=sin((pi/17)*n);

stem(x1)

axis([0 35 -1.5 1.5])

grid on

my problem is in n values are not correct, 35 must be not included

Answer 1

If you want n to have integer values greater than zero and strictly less than 35 you can define

n = 0:34

If you don't require the values to be integers but just want them equally spaced up to some value slightly less than 35 you could use

tol = 1e-6; % amount less than 35 that you want to reach
nMax = 35 - tol; % final value for n
numPoints = 100; % number of equally space points that you want
n = linspace(0,nMax,numPoints)
