引数までの多項式のべきすべてのリストを返します。
(%i1) load("makeOrders")$ (%i2) makeOrders([a,b],[2,3]); (%o2) [[0, 0], [0, 1], [0, 2], [0, 3], [1, 0], [1, 1], [1, 2], [1, 3], [2, 0], [2, 1], [2, 2], [2, 3]] (%i3) expand((1+a+a^2)*(1+b+b^2+b^3)); 2 3 3 3 2 2 2 2 2 (%o3) a b + a b + b + a b + a b + b + a b + a b 2 + b + a + a + 1 |
ここで、
[0, 1]
は項 bに関連づけられ、
[2, 3]
は a^2 b^3に関連づけられます。
この関数を使うには最初に load("makeOrders")
と書いてください。
