[Blindmath] Accessible Matlab

[Godfrey, Jonathan]

Hi Doug,

Start with Octave then. It uses the same syntax, but may not have every function offered by Matlab. It won't take long to find out though.

     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
