Hello, I have a question that is probably very simple but I still couldn't figure it out due to my quite limited MATLAB knowledge. As a part of Signal Processing course, I need to define an 8 point sequence, x[n]=1, n=0,1,2,3, and x[n]=0 for n=4,5,6,7.

I have been trying to create it by simply typing:

x=[1 1 1 1 0 0 0 0];

But it starts from 1, instead of 0. How can I correct it?

Hey,

In Matlab the vectors begin at 1. So you have to live with it and your sequence x[n] for n = 0,1,2,3,...,7, should be changed to x[n] = n = 1,2,3,...,8 in your code.
