Yes, exactly. > On Thu, Feb 27, 2014 at 6:48 PM, varun chopra <[email protected]> wrote: > > > Can you send me the software? The one I downloaded from internet is not > > working. There are sources and binaries on download page. To start coding pre-build binary is enough: binary contains Spad compiler and can dynamically load new code. So having binary should be enough to repeat example on http://axiom-wiki.newsynthesis.org/ProgrammingSPAD In fact, for start it may be easier to start with "interpreter": you can try command on FriCAS command line and add working ones to a file creating a little function. Important help is FriCAS browser, it allows you to see what functions are available in given domain (for example for differential operators). If binary does not work for you should report all details. It works for other folks, so without details we can not say why it does not work for you. If dowload does not work for you say that clearly: if really needed I can send you binary via e-mail (but that would be very strange). BTW: axiom-wiki site allows you to develop code via Web, crate a sandbox page, use preview mode to make changes and save when it works (or you need a break). But having FriCAS locally is much more convenient. -- Waldek Hebisch [email protected] -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
