Maxima Function
pui (L, sym, lvar)
decomposes the symmetric polynomial sym, in the variables in the
list lvar, in terms of the power functions in the list L.
If the first element of L is given, it will be the size of the
alphabet, otherwise the size will be the degree of the polynomial
sym. If values are missing in the list L, formal values of
the type p1, p2 , etc. will be added. The polynomial
sym may be given in three different forms: contracted (elem
should then be 1, its default value), partitioned (elem
should be
3), or extended (i.e. the entire polynomial, and elem
should then
be 2). The function pui
is used in the same way.
(%i1) pui; (%o1) 1 (%i2) pui ([3, a, b], u*x*y*z, [x, y, z]); 2 a (a - b) u (a b - p3) u (%o2) ------------ - ------------ 6 3 (%i3) ratsimp (%); 3 (2 p3 - 3 a b + a ) u (%o3) --------------------- 6
