How do I represent time domain plot as vector

I have the following data and their values:

x   contains 

             <1 x 40000>

 y contains

                <1 x 40000>

I did a plot as follows:

vsign = plot(x,y);

How do I represent vsign in vector form of

   <1 x 40000>

instead of the scalar value of 174.0023 am getting?

When you assign an output to the plot command, what you get is a "handle" to the plotted line, which you can use to edit some of its properties. This is described in

>> doc plot

That, as you see, is a scalar. You can use

>> get(vsign)

to see those properties and their values.

What is it that you want instead?
