Program help needed

Use mat2list(). It will give you a list of components with comma separators (but it won't be a vector in the normal sense).

Quote:2. I have read several posts describing CAS programming, but context is mostly dated around February 2014. With revisions, changes seem to have made creating a function: f(x):=anything, no longer show up in the [shift] [program] list, so cannot be edited therein. Is there another way to get CAS programs into the program editor?

Help appreciated!

If the function was created by typing f(x):=blah, then simply type f on the command line and the function's "source" will be copied onto the history. Copy this output and then in the program editor, create a CAS program and paste the contents into this program. You can now get rid of the one in the CAS environment via purge(f) and just use the one that shows up in the program catalog.
