Computes Dawson's integral of x element-wise.

Dawson's integral is defined as exp(-x**2) times the integral of exp(t**2) from 0 to x, with the domain of definition all real numbers.

Dawson's function is odd.

>>> tf.math.special.dawsn([-1., -0.5, 0.5, 1.]).numpy()
array([-0.5380795, -0.4244364, 0.4244364,  0.5380795], dtype=float32)

This implementation is based off of the Cephes math library.

x A Tensor or SparseTensor. Must be one of the following types: float32, float64.
name A name for the operation (optional).

A Tensor or SparseTensor, respectively. Has the same type as x.
