Determine inequality

returns a logical array
with elements set to logical `A`

~= `B`

`1`

(`true`

) where
arrays `A`

and `B`

are not equal; otherwise, the
element is logical `0`

(`false`

). The test
compares both real and imaginary parts of numeric arrays. `ne`

returns logical `1`

(`true`

) where
`A`

or `B`

have NaN or undefined
`categorical`

elements.
