[...] How much memory does your system have? How complicated are the matrix elements themselves? The symbolic inversion of larger matrices requires a lot of memory. Formatting of the result for printing or display adds to the memory requirements. I don't think there is a bug; I can invert an 8x8 matrix with simple elements on my system with 64 MB memory.
