Value

a reference to a Macaulay2 ideal

Arguments

...: ...
raw_chars: if TRUE, the character vector will not be parsed by mpoly::mp(), saving time (default: FALSE). the down-side is that the strings must be formated for M2 use directly, as opposed to for mpoly::mp(). (e.g. "x*y+3" instead of "x y + 3")
code: return only the M2 code? (default: FALSE)
x: a listing of polynomials. several formats are accepted, see examples.
ideal: an ideal object of class m2_ideal or m2_ideal_pointer
ring: the referent ring in Macaulay2
I, J: ideals or objects parsable into ideals
e1, e2: ideals for arithmetic
