How to load file with variable length lines?

Suppose I have a file called x.txt with three lines that looks like this:

1 2
1 2 3

I would be happy to have it load into Octave with, say, this form:

1 NaN NaN
1  2  NaN
1  2   3

That is, I want to pad the ends of shorter lines with NaNs (or anything else you can come up with). Is there an Octave function that will do this for me?

I see the function "aload" but I can't get it to do what I want. If no such function exists, I may be able to create one.
