This appears to be fixed in the new symbolic package.

This is because the heaviside function in Octave is a numerical implementation, not a symbolic implementation as it is in Matlab. Retitling this bug as a feature request to implement this function symbolically.

Please note that the symbolic package is largely unmaintained and needs a lot of work. See the following links.

Dear Developers :)

I hope I do not duplicate the bug.

The following code from my university classes, which worked on MATLAB 13, produces an error on octave:

It gives the following error:

Line 12 is where the heaviside function is called.

Even the simplest commend, which I suppose would work on matlab (I am not a MATLAB expert yet, I just started learning, so I am not 100% sure) for example:

gives the same error.
