Dual.__ne__(other)

Return element-wise (value and derivative vector) inequality comparison of self and other.

Parameters

selfDual

otherint, float, Dual

Returns

outtuple

Examples

Dual number and scalar:

>>> ad.Dual(42) != 5
(True, array([True]))

Two dual numbers (univariate):

>>> ad.Dual(5, [2]) != ad.Dual(5, [1])
(False, array([True]))

Two dual numbers (multivariate):

>>> ad.Dual(2, [4, 2]) != ad.Dual(5, [1, 2])
(True, array([True,  False]))
