Dear all, I want to extract terms from polynomial formed using syms. Here is the code
smys x a
y= x^4 + a*x^3 + 2*a^2*x + 5;
now i need to extract the terms x^4 a*x^3 etc into a new variable that can be used at some other place. like
w=x^4;
r=a*x^3;
d=w+r;
Kindly help on this thanks.

Didn't you answer your own question? Isn't w,r,d are what you want? Am I missing something?

syms x a
y= x^4 + a*x^3 + 2*a^2*x + 5;
[variable,coefficient]=coeffs(y,x)
