jax.numpy.isposinf#

jax.numpy.isposinf(x, /, out=None)[source]#

Return boolean array indicating whether each element of input is positive infinite.

JAX implementation of numpy.isposinf.

Parameters:

x – input array or scalar. complex dtype are not supported.

Returns:

A boolean array of same shape as x containing True where x is inf, and False otherwise.
