matlab - Finding a Polynomial Root -


i need solve problem involves finding root of following polynomial:

(l) = [(w.n.l + (1+r)k - k1 - g)^(-(1/sigma))].w.n - gamma.(l)^(1/phi),

the problem monotonicity of f(l) depends on set of given parameters (w,n,r,k,k1,g,sigma,phi).

when [(1+r)k - k1 -g] < 0, f(l) not monotonic, having more 1 root. can me find these roots on matlab?
