how plot X=const
显示 更早的评论
I have a Y vector comprising a set of values (eg Y = (2.5, 34, 65, -12, etc ...) I have another G vector comprising a set of values (eg G = (12.5, 5.789, 4.6102, 21.09, etc ...).
I would like to draw on the same graph the curve defined by the vector Y, and, the vertical lines of equation X = 12.5, X = 5.789, X = 4.6102, X = X 21.09 = ... etc (the values defined by my G vector...
How can I do ?
!!!! Y and G have not the same length

Please, instead of repeating the same question, provide more details that would help us understand what it is you actually want. An image would be quite suited for that in this case.

x = 1:100;
y = cos(x .* 2 .* pi ./100);
X = rand(1,10) .* 100;
Y = interp1(x,y,X);
plot(x,y,'r-','Marker','*');
hold on
stem(X,Y)
