[Blindmath] Accessible Matlab

Wed Feb 1 15:28:51 UTC 2017

Hello all.
My name is Lucas and this is my first message to this list since I joined it yesterday. I am from Brazil, currently living in Minneapolis.

Doug I am not sure what your question is, but regarding accessibility with matlab I was really concerned with this a couple of weeks ago since I am taking a linear algebra course. I started using matlab via terminal command line on the mac and it works really well.
All the functions and everything that I encountered since now works in the command line as it would on the interface of matlab.

I hope that this helps.

Thank you.

Best regards.

Lucas Nadolskis.

What version of Mac are you using?  Is access through a real keyboard rather than a touch screen?  I suspected that an Apple platform with VoiceOver might work, but neither the Apple people nor the Matlab people could tell me.  I think I will try Octave since I've already invested in a high-end HP Windows 10 system.  I'll keep your route in mind though.  Thanks.

Either way, most of what you mentioned that you will be doing can be performed using Scripts, functions and the built in command line. Most of the toolboxes that I have used are accessible. However, if you’re planning to use a toolbox that requires some form of graphical input, you might want to contact the developers of that particular toolbox to see if those functions can be achieved using text commands. As Jonathan stated there are other programs, but if you are planning to use Mathematica’s Graphical User Interface, I can tell you right now, that at least on the mac, it is not accessible at all. Last, you can always use the aforementioned programs in Batch mode, and that tends to be more accessible depending on the configuration of the software.

In '84, I had a summer job at IBM Rochester, MN at which I learned APL to work on their code for disk drive read-back error simulation.  Matlab is the diminished stepchild of APL, but it has the advantage of using only ASCII characters.  Anyway, I read of Octave somewhere and sent their people an e-mail inquiring about accessibility, but never heard back.  If you have a suggestion about which to use, I'd be grateful.

I would have thought that you could investigate this with a colleague running a more recent version of Matlab. I'd like to know if you do manage this experiment (successfully or not) so I can update the above web resource.

I’m presently using an old version of Matlab that is audio accessible, but it’s a 32-bit version that I’m running on a WinXP box, and the 4GB RAM is barely adequate.
