Hi,

I programmed an implicit numerical scheme which requires maple to find the inverse of a 400x400 matrix.

Once it succeeds, it has to multiply a 400x1 matrix by this 400x400 inverse 1500 times.

how long should I expect it to take? Its already been running for minutes, but I have no idea when I could expect it to finish.

in half an hour? 5 hours? 2 days?

thanks for any ideas..
