[comp.sys.next] Mathematica: large matrices

agm@cs.brown.edu (Axel Merk) (03/20/91)

I need to do some 'simple' transformations on a 260x260 matrix of
floating point values, but Mathematica does not seem to like it too
much.
When pasting the matrix into Mathematica from a text file, I inserted
return signs in order not to exceed the maximum size allowed for a
line. Doing this allowed me to paste it.
Assigning the matrix do a variable, i.e. evaluating it, results in
error messages on the console indicating "hash invariants" and a
blow-up of the swapspace.

Are there known limits to the size of a matrix and can they be
increased? I'm aware that I'm dealing with lots of memory and am
willing to allocate the appropriate swapspace, but I have the feeling
that simply assigning a matrix to a variable should not cause the
problem. 

Thanks for any suggestions,

Axel
