RE: How much memory is needed?


Just for fun, I tried doing the inverse of:

hb = Table[x/(i + j), {i, 60}, {j, 60}];
Inverse[hb]

On a MacBook with WinXP, 32-bit Mathematica v6, it crashed Mathematica in an odd
way after about 3 minutes. (I got a dialog box with a C program error -
never seen that before).
Under OSX, 64-bit Mathematica v6, it seems to run fine - but didn't finish after
30 minutes, so I stopped the program.
I was using 2GB, dual-core Intel. Hope this helps a bit.
