convert list of lists to matrix



Hi,

I'm new to maxima and have a problem, I don't find a solution for.

rk from the package dynamics returns a list of lists. Something like:

[[0, 1 , 3],[1 , 2, 5]]

I would like to plot that, and for that reason need it as a matrix,
like:

matrix([0,1,3],[1,2,5])

I just can't figger out, how to do that. (I looked through the
documentation, and googled around, tried various possibilities, but
didn't get to a solution ...)

Many thanks for your help!
