Logic functions

Hint

Truth value testing

`all`	Test whether all array elements along a given axis evaluate to `True`.
`any`	Test whether any array element along a given axis evaluates to `True`.

`isfinite`	Test each element \(x_i\) of the input array x to determine if finite.
`isinf`	Tests each element \(x_i\) of the input array x to determine if equal to positive or negative infinity.
`isnan`	Tests each element \(x_i\) of the input array x to determine whether the element is `NaN`.
`isneginf`	Test element-wise for negative infinity, return result as bool array.
`isposinf`	Test element-wise for positive infinity, return result as bool array.

`iscomplex`	Returns a bool array, where `True` if input element is complex.
`iscomplexobj`	Check for a complex type or an array of complex numbers.
`isfortran`	Check if the array is Fortran contiguous but not C contiguous.
`isreal`	Returns a bool array, where `True` if input element is real.
`isrealobj`	Return `True` if x is a not complex type or an array of complex numbers.
`isscalar`	Returns `True` if the type of element is a scalar type.

`logical_and`	Computes the logical AND for each element \(x1_i\) of the input array x1 with the respective element \(x2_i\) of the input array x2.
`logical_or`	Computes the logical OR for each element \(x1_i\) of the input array x1 with the respective element \(x2_i\) of the input array x2.
`logical_not`	Computes the logical NOT for each element \(x_i\) of input array x.
`logical_xor`	Computes the logical XOR for each element \(x1_i\) of the input array x1 with the respective element \(x2_i\) of the input array x2.

`allclose`	Returns `True` if two arrays are element-wise equal within a tolerance.
`isclose`	Returns a boolean array where two arrays are element-wise equal within a tolerance.
`array_equal`	`True` if two arrays have the same shape and elements, `False` otherwise.
`array_equiv`	Returns `True` if input arrays are shape consistent and all elements equal.
`greater`	Computes the greater-than test results for each element \(x1_i\) of the input array x1 with the respective element \(x2_i\) of the input array x2.
`greater_equal`	Computes the greater-than or equal-to test results for each element \(x1_i\) of the input array x1 with the respective element \(x2_i\) of the input array x2.
`less`	Computes the less-than test results for each element \(x1_i\) of the input array x1 with the respective element \(x2_i\) of the input array x2.
`less_equal`	Computes the less-than or equal-to test results for each element \(x1_i\) of the input array x1 with the respective element \(x2_i\) of the input array x2.
`equal`	Calculates equality test results for each element \(x1_i\) of the input array x1 with the respective element \(x2_i\) of the input array x2.
`not_equal`	Calculates inequality test results for each element \(x1_i\) of the input array x1 with the respective element \(x2_i\) of the input array x2.
