PSUBST Solve p1 o p2
PSUBST(p1,p2) returns the polynomial coefficients for p1 o p2, i.e. returns p2 subsituted for the variable of p1. The resulting vector is length (LENGTH(p1)-1)*(LENGTH(p2)-1)+1.
For example:
p1=f(y), p2=f(x) ==> PSUBST(p1,p2)=p1(p2(x))
p1=y^2+4y+6, p2=x+1 ==> PSUBST(p1,p2)=x^2+6x+11
