Hi
I have a very long polynomial in coefficients u,v,w,z stored in variable f and I would like to truncate high order terms. when I try to calculate: "taylor(f, [u, v, w, z],'Order', 5) " I do not get the result I want but an expression starts with "mtaylor(....) " or some massage that matalb cannot compute it. How can I solve it ? thanks

u,v,w,z are syms and f is not a function handle ?
Please show us your complete call to "taylor"
Best wishes
Torsten.

Not all functions have taylor expansions.

the function I have is a homogeneous polynomial. all I want is to truncate the high powers.Maybe there is another way to do it?
