Hello, all of you.
Some time ago there was a discussion about implementing rationals in
Guile with the help of GOOPS. Recently, I needed an exact matrix
inversion and implemented rationals in that way. Even if it is still
imperfect and might be also too slow, it might be of help.
I have put some code on the Web:
which is used by
(LR decomposition with pivoting, matrix inversion)
I don't know if this is really the best way to construct the whole
numerical tower (how does SCM do it?), and would be interested in
