NCo.BMultiply
Multiplication of two polynomials in a free monoid ring over the binary field F_{2}={0,1}.
Syntax
NCo.BMultiply(F1:LIST, F2:LIST):LIST
Description
Please note: The function(s) explained on this page is/are using the ApCoCoAServer. You will have to start the ApCoCoAServer in order to use it/them.
Please set ring environment alphabet (or set of indeterminates) X and word ordering via the functions NCo.SetX and NCo.SetOrdering, respectively, before calling this function. The default ordering is the length-lexicographic ordering ("LLEX"). For more information, please check the relevant functions.
@param F1, F2: two polynomials in the free monoid ring F_{2}<X>, which are left and right operands of multiplication, respectively. Each polynomial is represented as a LIST of words (or terms) in <X>. Each word is represented as a STRING. For example, xy^2x is represented as "xyyx", and the identity is represented as the empty string "". Thus, the polynomial f=xy-y+1 is represented as F:=["xy", "y", ""]. The zero polynomial 0 is represented as the empty LIST [].
@return: a LIST which represents the polynomial equal to F1*F2.
Example
NCo.SetX("xX");
NCo.SetOrdering("LLEX");
F1:=["xX",""];
F2:=["Xx",""];
NCo.BMultiply(F1,F2);
["xXXx", "xX", "Xx", ""]
-------------------------------
NCo.BMultiply(F2,F1);
["XxxX", "xX", "Xx", ""]
-------------------------------
NCo.BMultiply([],F1);
