[Blindmath] Accessible Matlab

[Doug and Molly Miron]

     Hi,

I'm doing numerical electromagnetics.   No matter what the method, one fills 
a large, dense matrix and a  source vector to solve the problem.  As you 
probably know, Matlab stands for matrix laboratory, so it is suited to the 
nature of the problems.  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.

Regards,
Doug Miron

Hi Doug,

Offering advice on what alternatives exist without knowing what you are 
using Matlab for is a little difficult.

You could use Octave, Maxima or R to do all the functions available on a 
standard scientific calculator in an interactive mode of working.

You could use Mathematica, R, Octave,  or Maxima if you need to do higher 
level work; all of these programs can be used in batch mode. Your choice 
will almost certainly depend on the type of higher level work you are doing 
as the coverage and user-friendliness will differ among these options.
See https://r-resources.massey.ac.nz/batchprocessing/
For instructions on batch processing with these options.

Matlab did have a command line to allow batch processing of script files, 
but I've not had a machine with Matlab on it for some time to test the 
current settings needed. 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.

Jonathan

Good day all,

Alternatively, does anyone know of a Matlab-like scientific computing 
package that is audio accessible?  I’ve tried SciLab and FreeMath without 
success.  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.

Thanks,
Doug Miron
