jax.numpy.isposinf#

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

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

JAX implementation ofnumpy.isposinf.

Parameters:

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

Returns:

A boolean array of same shape asx containingTrue wherex isinf, andFalse otherwise.
