Hello!

1) I want to transform a polynomial in variables x_1, ... , x_n into function K^n -> K

Example:

given y[10] := x[10]+x[1]^2+x[2]*x[5]+x[3]*x[8]

i want to view y[10] as a function and evaluate it at point (x_1, ..., x_n)

 

2) Given m such polynomials y[i] I want to define a funktion K^n -> K^m by viewing every y[i] as a coordinate function

Example:

f:=(y[1],...,y[m]) every y[i] beeing a polynomial in x_1, ..., x_n

Then i want to evaluate f at (x_1, ..., x_n) like that: f(x_1,...,x_n):=(y[1](x_1,...,x_n),...,y[m](x_1,...,x_n))

 

Is there a way to do these things in maple? Thank you very much for your help!
