[Blindmath] accessible math packages

[Joseph C. Lininger]

Good afternoon/evening folks,
I'm wondering which math solutions (matlab and such) are accessible
under windows with window-eyes and/or under Linux using speakup screen
reader. At this exact moment, I need to be able to do operations you'd
typically do in Linear algebra, reduce matrices, invert matrices,
perform vector operations, etc. I will almost certainly need to use it
later on in my math studies for more involved things as well. Can anyone
make suggestions? I tried Matlab because that's what my instructor wants
the class to use for large matrices, but discovered the installer didn't
even work. (java it looks like) Is that how the entire package is? I'm
also interested in using R for some other math stuff I'm working on if
that is accessible, and would like input on these packages and other
suggestions if you have them. Thanks in advance.
Joe
