limits of 'invert' [message #46348]

Dear IDL & Maths experts:

Is there a limit for the 'invert' or 'la_invert', program to calculate
the inversion of a square matrix, provided by IDL?

When my matrix is 150x150, 'invert' return immediatelly, but when it is
'15000x15000', 'invert' runs for more than a day. I am wondering
whether it is in some infinite loop, or it simply needs that long.

What is the reasonable upper limit that 'invert' or 'la_inver' can
operate?

Thanks,

Q
