Hi.

I'm trying to plot a matrice against a vector using Matplotlib.
Something like we can do with Matlab :

plot(x,Y)

where
    x is an Numeric.array of shape (n,)
    Yis an Numeric.array of shape (m,n)

Is there a way to do that in Matplotlib?
Does the Matlab command "hold" have a equivalent in Matplotlib? I didn't find it, and if it exists, then I could plot the lines of the matrix Y one by one.

Thank you for any information.
