# erf_zeros

scipy.special.erf_zeros(nt)

  Compute the first nt zero in the first quadrant, ordered by absolute value.

  Zeros in the other quadrants can be obtained by using the symmetries erf(-z) = erf(z) and erf(conj(z)) = conj(erf(z)).

  Parameters:
    ntint

      The number of zeros to compute

  Returns:
    The locations of the zeros of erfndarray (complex)

      Complex values at which zeros of erf(z)

  Examples

      >>> from scipy import special
      >>> special.erf_zeros(1)
      array([1.45061616+1.880943j])

  Check that erf is (close to) zero for the value returned by erf_zeros

      >>> special.erf(special.erf_zeros(1))
      array([4.95159469e-14-1.16407394e-16j])
