The function to invert a matrix was changed some time ago in an attempt to run faster....
(1) About execution speed: makelist(2^((-n)/2), ...) is creating a list with an exact...
get lost socket connection - and otherwise takes too long
gives wrong answer and asks redundant questions - integrals
incorrect matrix inversion
says integral is divergent when it clearly is not
division by zero in simplify_sum
$ sign is not in index and causes eternal hang up - Interrupt does not work
