Memory Allocation, Plotting

[Thomas Viehmann]

Hi,

I'm using "debianized" Octave 2.1.31 and encountered two problems:
1. How can I change the labels "line x" in my plots?
2. I've tried a "diag(x)" with a 10000 item vector (yes, that
   was part of a somewhat awkward attempt to avoid for loops)
   which resulted in (of course) an out-of-memory error. So the
questions
   that I derived are
   - for my concrete problem: Is there an elegant way of
     calculating diag(x)*y with x ŠÜin R^n, y ŠÜin R^{n*m}?
   - for the diag problem in a more general way: are there
     routines/plans to implement routines for sparse matrices?

Greetings+Thanks

Thomas
P.S.: cc of answers to me would be appreciated
