Re: Derivative function

[A S Hodel]

Symbolic derivatives, no, e.g.,

y = derivative('sin(x)','x');  (derivative of sin(x) with respect to x)

is not available in Octave.  Someone wrote to this list recently (in 
the last week or so) about
using macsyma for symbolic work.

Numerical derivatives:
t = (vector of values)
y = sin(t);

dydt = diff(y) ./ diff(t)

can be done.
