Polynomial min/max using coefficients vector?
显示 更早的评论
Hello Experts,
Consider I have polynomial and a vector p with it's coefficients. What function in Matlab gets such vector p and computes max and minimum.
Thanks a lot in advance!
I need both maximum and minimum.

Suppose you have a polynomial
x^3 - 2*x - 5
c=sym2poly(x^3 - 2*x - 5) will give you the vector coefficients:
c =
1.00 0 -2.00 -5.00
minmax(sym2poly(x^3 - 2*x - 5))
ans =
-5.00 1.00
minmax(sym2poly(polynomial)) will give you the minimum and maximum of the coeffiecients.
Hope this was useful
