laguerre

DOCUMENT laguerre(a,x)
  Given the coefficients a(1:m+1) of the m'th degree
  complex polynomial Sum(a(i)*x^(i-1)) and a guess x, returns a root.
  See Numerical Recipes (Press, et. al., Cambridge Univ. Press 1988),
  section 9.5.

zroots

DOCUMENT zroots(a)
  returns the vector of (complex) roots of the (complex) 
  polynomial: Sum(a(i)*x^(i-1)) using Laguerre's method.
  The roots are sorted in order of increasing real parts.  Call with
  non-zero imsort keyword to sort into increasing imaginary parts.
