Hi!
The error you're encountering occurs because the loop index i in the second loop exceeds the range of valid indices for the xn_ch array. In the last iteration of the loop, i becomes 6, while xn_ch has only 5 elements.
n = 5;
for i = 1:n
xn_ch(i) = cos(pi * (2 * i - 1) / (2 * n + 2));
end
for i = 1:n-1
xch = linspace(xn_ch(i), xn_ch(i+1), 11);
end
xn_ch
To solve this issue, you can modify the loop to iterate from 1 to n-1 instead of n.
I hope this helps!
