Dear Sumant,
You have sent an excellent example!

Suppose I create the matrix
M:=matrix([[random()$PF(19) for i in 1..3] for j in 1..3])
Assuming the determinant is non-zero, then I can invert the matrix in the
finite field PF(19). But suppose I enter
N:=matrix([[random()$ZMOD(20) for i in 1..3] for j in 1..3])
If the determinant is

Oddly enough, I was just looking at Dirac Deltas (from a physics
standpoint, a CAS with a good handle on the Dirac Delta is a Good
Thing).
It looks like a mathematically rigorous definition of the Dirac Delta
would require generalized functions (a.k.a distributions). I don't
know much about

Incidentally it looks like the key papers are in French - does anyone
know if there are authoritative translations anywhere? If not it
looks like some quality time with
