Is it possible to use one array instead of three in mlab.plot3d?

Hi, in the following code it seems that passing one argument as a list of points is foreseen:

However, the following part later prevents it:

Am I looking at it right, or is it always needed to separate the Xs, Ys and Zs into three args?
