While experimenting with symbolic manipulation I was able to
crash octave. This may be due to operator error; I don't
know how to use octave-forge's symbolic toolbox, so I'm just
feeding random stuff at it. Here is a transcript:

Somehow I had forgotten to close this earlier right after Paul's
reply... Fixing that now.
Thanks, Dirk

| You need to say 'symbols' before using the symbolic package. Putting

|
| octave:1> symbols
|
| Then you need to define you symbolic variables:
|
| octave:2> x = sym('x')
| x =
|
| x
|
| And the expressions which use them:
|
| octave:3> A = Cos(x)
| A =
|
| cos(x)
|
| Before you can manipulate those expressions:
|
| octave:4> differentiate(A,x)
| ans =
|
| -sin(x)
|
| Note that if you don't like using Cos(x) you can use the dispatch
| mechanism to define cos(x) -> Cos(x) for symbolic x as follows:
|
| octave:5> dispatch('cos','Cos','ex')
| octave:6> A = cos(x)
| A =
|
| cos(x)
| octave:7> differentiate(A,x)
| ans =
|
| -sin(x)
|
