Hello, everyone.

`I've had Octave loaded on my PowerBook for a long time (v. 2.1.73)
``and have used it *very* lightly for very simple things, mostly to
``obtain simple plots. Now I have a good reason to upgrade Octave and
``learn to use it better: I need to solve a PDE. Henry Mollet sent me
``instructions on upgrading to v. 3.x some time ago and I've kept those
``instructions, so I can upgrade. (Thanks, Henry!) :-)
`

`Now my questions. The questions are about Octave, but please note
``that I don't have any experience with numerics or coding at all, so
``please be gentle.
`
1) Can Octave be used to solve an equation like this:
u_{tt}(x,t) - C * u_{xx}(x,t)
= B * \int_{-infty}^{+\infty} K(x-y,y) * u(x-y,t) * u(y,t) dy,
where B, C are constants and K is some kernel.

`2) If the answer is yes, then where should I look in the
``documentation (or elsewhere) to learn (in baby steps) how to solve
``such an equation eventually? (I think one good step along the way,
``after some initial baby steps solving some baby equations, would be
``to solve the inviscid Burgers equation:
`
u_t + u*u_x = 0, u = u(x,t).)
Thanks for your help.
---John.
