Hello,
I have a vector G (with 120 values).
I'd like to plot a vertical line for each value of this vector in a graph having an other curve. How can I do this?
thank you

Perhaps the stem() function?
g = rand(1, 10);
plot(g, 'ro-', 'LineWidth', 2);
hold on;
stem(g);

How about this:
Y = [2.5, 34, 65, -12]
G = [12.5, 5.789, 4.6102, 21.09]
plot(Y, 'ro-', 'LineWidth', 4);
grid on;
hold on;
stem(G, max(Y)*ones(1, length(G)), 'Marker', 'none', 'LineWidth', 4);
Note: Y and G don't have to have the same number of elements. ALso, you have not defined an X for the Y values so I'm just assuming X is the index number. For the "G" lines, I'm having them go just from 0 up to the max Y value since you gave no indication of where the lines start or stop.

Another option to go the full height of the graph is to use line() function:
Y = [2.5, 34, 65, -12]
G = [12.5, 5.789, 4.6102, 21.09]
plot(Y, 'ro-', 'LineWidth', 4);
grid on;
hold on;
yl = ylim();
for k = 1 : length(G)
x = G(k);
line([x, x], yl, 'Marker', 'none', 'LineWidth', 4);
end
