program:

clear all

function z = l(xx, i, x)
    n = size(x);
    pr = 1;
    for j = [1:1:(i - 1) (i + 1):1:n(1)]
        pr = pr * (xx - x(j)) / (x(i) - x(j));
    endfor
    z = pr;
endfunction

function z = L(xx, x, y)
    n = size(x);
    sum = 0;
    for i = 1:1:n(1)
        sum = sum + l(xx, i, x) * y(i);
    endfor
    z = sum;
endfunction

n = 4;
x = [1 3 5 7]';
y = [2 2 4 4]';

L(2, x, y)
L(4, x, y)
L(6, x, y)
disp("Hello world!")

But I can run octave-cli from any place via terminal directly without any problems. So I don't understand why it happens.
