# numpy.roots

`numpy.``roots`(p)

  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]

  Parameters: | p : array_like of shape(M,) Rank-1 array of polynomial co-efficients.
  Returns: | out : ndarray An array containing the complex roots of the polynomial.
  Raises: | ValueError: : When p cannot be converted to a rank-1 array.

  Examples

      >>> coeff = [3.2, 2, 1]
      >>> print np.roots(coeff)
      [-0.3125+0.46351241j -0.3125-0.46351241j]
