specific values of a plot

I have an *.m file that solves a 2nd order differential equation numerically (using ode45) and also i have it plotted [plot(t,x(:,1))].

Is there any way i can call for some specific values of the plot like for example the speed or position for t=1 sec ?

Thanks in advance !

You can use the handle to each line on your plot to obtain the XData and YData as follows.

Test = line(...); or Test = plot(...) xD = get(Test,'XData'); yD = get(Test,'YData');

This will give you exact numbers for the lines on your plot.

Hope this helps!

Thank you very much. Not only is the answer stored, but i can also use it in further calculations in the form yD(number). Unfortunately though, since it is a numerical method, i do not know in advance the number of evaluations needed thus it is a little difficult to use. It is very helpful though, thank you again!
