The symbolic package has been replaced with a completely new implementation based on SymPy. Closing this bug report since it applies to the old unmaintained symbolic package.

The symbolic package in Octave is unmaintained and badly broken. Even when you get it to not crash, it doesn't do anything all that useful. For example, it doesn't work on arrays.

If you are interested in fixing this, this is an outstanding GSoC project for Octave:

I have the following problem on a Mac with OSX 10.8.3.

After installation of ginac from MacPorts, I have installed the symbols package with the usual command:


> pkg install symbols-1.1.0.tar


When trying to use the symbolic package octave crashes:


macmac2:$ octave

Any idea of what is wrong? As a side remark, the ginac package seems to work ok, as is seen from the following example:


macmac2: $ ginsh
