jax.numpy.isneginf#

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

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

JAX implementation ofnumpy.isneginf.

Parameters:

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

Returns:

A boolean array of same shape asx containingTrue wherex is-inf, andFalse otherwise.
