Calculate the value of a symbolic experession

Leo Baumann
Hello,

I am newbie to Octave and have the problem to calculate the value for a
symbolic expression for an argument. -

 >> ux
ux = (sym)

                    /      75*pi  \                    / 25*pi  \
   Heaviside|t - ---------|   Heaviside|t - ---------|
                    \    310895263/            \    310895263/
                   ------------------------ + ------------------------
                                      6                          2

 >> td
td =   2.5262e-007
 >> t=2*td
t =   5.0525e-007
 >>

I don't find the syntax for calculation of ux(t) in the help files. I
want to calculate ux at the point t.

Anyone can help me, please?

Regards - Leo
