## Calculate the value of a symbolic experession

 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?
