    line([x(i) x(i+1)],[3 4],'linewidth',2,'color','black')
end

Answer 1

[Birdman]

When i=8, you try to reach 9th element of x at this line:

 line([x(i) x(i+1)],[3 4],'linewidth',2,'color','black')

when x(i+1) is operated. You have 8 element in your x array, so fix that.

Thank you for your suggestion.

Answer 2

[Walter Roberson]

You initialize x=1:8 so the last entry in x is x(8)

You loop for i=1:8, and inside your loop you refer to x(i) and x(i+1) . When i = 8, that is x(8) and x(8+1) = x(9). However, there is no x(9) in your array.
