FriCAS Maths Program

FriCAS is a fork of the Axiom program as described here.

FriCAS seems to be the most activly developed of the Axiom forks and this is where I would reccomend potential new users to go.

If you are a potential new user, I suggest going to the website here and download the binaries and try it. For Linux operating systems (which is the only version I have personally tried) I found it quite easy to install and try. Compiling from source is harder but I don't see why new users should need to do that.

I did have a problem with older versions of openSuSE where virtual memory limit was set low by default. I think that problem has gone away with newer versions of openSuSE but, just in case, I have documented what I saw on the page here.

After that start reading the Axiom Book in either PDF or html form.

At the moment documentation about FriCAS is spread between:

I think Axiom/FriCAS is very powerful and deserves to be more widely used. However it does have some issues and I have put my own personal 'wish list' is on the page here.

If you have issues with FriCAS why not go to the mailing list.

Installing from Binary

Goto the FriCAS Sourceforge page here and download the binary (in this case fricas-1.2.6.amd64.tar.bz2)

Unzip the files as shown here:

fricas unzip

I then moved the extracted files into my /usr/local directory (in super user mode - in other words as root):

move fricas

Starting Fricas

We can then run FriCAS as follows:

martin@linux-rks1:~> /usr/local/bin/fricas
Checking for foreign routines
AXIOM="/usr/local/lib/fricas/target/x86_64-unknown-linux"
spad-lib="/usr/local/lib/fricas/target/x86_64-unknown-linux/lib/libspad.so"

Troubleshooting

There are some dependencies but these should be usually be present in all desktop Linux systems:
