numpy.roots() function return the roots of a polynomial with coefficients given in p. The values in the rank-1 array p are coefficients of a polynomial. If the length of p is n+1 then the polynomial is described by: p[0] * x**n + p[1] * x**(n-1) + … + p[n-1]*x + p[n]
Syntax : numpy.roots(p)
Parameters :
p : [array_like] Rank-1 array of polynomial coefficients.Return : [ndarray] An array containing the roots of the polynomial.
Code #1 :
# Python program explaining # numpy.roots() function # importing numpy as geek import numpy as geek p = [1, 2, 3] gfg = geek.roots(p) print (gfg) |
Output :
[-1.+1.41421356j -1.-1.41421356j]
Code #2 :
# Python program explaining # numpy.roots() function # importing numpy as geek import numpy as geek p = [3.2, 2, 1] gfg = geek.roots(p) print (gfg) |
Output :
[-0.3125+0.46351241j -0.3125-0.46351241j]
