[Blindmath] Computational software

Hi,

I've heard of sage but not magma. Given I expect there are others in the same boat, it would help us all if you would inform us about the accessibility for blind users when mentioning new software.

Cheers,
Jonathan

I'm at the University of Wisconsin Department of Mathematics. Around here, if people are going to use an open-source alternative to matlab, a lot of them use sage. A few use octave. The vast majority just use matlab, of course.
A lot of people also use magma. We have the paid version but there is a free student version as well.

Each sits in a  batch file that I click on in Windows explorer. In each case, I must know what files I want to have the software read the commands from and written to; sometimes the output files being written are specified inside the input file and not on the command line. Obviously, I must know the correct syntax for the software to get any programs working using the following command lines, and I have to admit that my tests have been very basic proofs of concept.

Octave and Matlab use practically the same code, but all of the others have their own syntax, which of course is not always thought of as an accessibility issue, although I would say having accessible documentation is a necessary criterion to impose on all software. Only Maxima has its own front end to generate code that could be put into an input file, and thankfully that GUI is pretty accessible. From my perspective, finding out what code is needed to do a job is the task of a student's lecturers, tutors etc. Getting people into a position to test that code is one of the things this list does well.

Can you recommend other numerical computation software that is powerful, accessible, and less expensive than MatLab? Secondly I would appreciate recommendations for symbolic solution applications such as Maple and Mathematica. I have used both of these and found Maple in particular to be quite accessible in command line mode. But I have not done such work in many years and fear that their accessibility is not as good now.
