In the documentation link: https://se.mathworks.com/help/matlab/ref/yline.html#mw_fe7a36af-ea48-44bc-8536-26d21d107674
we have the following code;
x = -2:0.25:2;
[X,Y] = meshgrid(x);
Z = X.*exp(-X.^2-Y.^2);
contour(X,Y,Z,30)
yl = yline(0,'--','y = 0','LineWidth',3);
It returns the following graph:
How to specify a range for the line? for example if i want to see the line only between x=-1 to x=1?

You cannot do that with yline() . You need to line() or plot() the line into place, and text() the label into place.
