People routinely use matrices larger than this in Sage. Works fine for me sage: m = matrix(ZZ, 3000, 3000) sage: m 3000 x 3000 dense matrix over Integer Ring The only limit that I know of for *dense* matrices is 4294967296 rows/ columns on 32-bit machines, (18446744073709551616 on 64-bit machines), and the memory constraints (which wouldn't let you have that many elements anyways). You're probably actually running out of memory. Did you check that? What exact command are you trying to run that fails? - Robert -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
