coefficients
coefficients({i,j,...},p) -- yields the coefficients and
monomials of the polynomial or matrix p with respect to variables
numbered i, j, ... . This has to
be completely redone, so I don't document it further, but it is used in
the factoring code.
coefficients(p) -- yields the coefficients and monomials of
the polynomial or matrix p with respect to all of the variables.
