Computes Dawson's integral element-wise.

Used in the notebooks

Used in the tutorials

Dawson's integral is defined as exp(-x**2) * int_0^x exp(t**2) with the domain of definition all real numbers.

This implementation is based on the Cephes math library.

x A Tensor with type float32 or float64.
name A name for the operation (optional).

dawsn dawsn evaluated at x. A Tensor with the same shape and same dtype as x.
