As other people commented, that should be faster if the original matrix was dense. In general, it is possible to write a procedure for inverting a matrix, writing the answer on the disk incrementally, appending it to a file - that may be slower, but removes the restriction on the RAM size (but one would need to have enough space on the hard drive instead) - I am not volunteering though.
