Logic functions#

Truth value testing#

all(a[, axis, out, keepdims, where])

Test whether all array elements along a given axis evaluate to True.

any(a[, axis, out, keepdims, where])

Test whether any array element along a given axis evaluates to True.

Array contents#

isfinite

isinf

isnan

isnat

isneginf(x[, out])

Test element-wise for negative infinity, return result as bool array.

isposinf(x[, out])

Test element-wise for positive infinity, return result as bool array.

Array type testing#

iscomplex(x)

Returns a bool array, where True if input element is complex.

iscomplexobj(x)

Check for a complex type or an array of complex numbers.

isfortran(a)

Check if the array is Fortran contiguous but not C contiguous.

isreal(x)

Returns a bool array, where True if input element is real.

isrealobj(x)

Return True if x is a not complex type or an array of complex numbers.

isscalar(element)

Returns True if the type of element is a scalar type.

Logical operations#

logical_and

logical_or

logical_not

logical_xor

Comparison#

allclose(a, b[, rtol, atol, equal_nan])

Returns True if two arrays are element-wise equal within a tolerance.

isclose(a, b[, rtol, atol, equal_nan])

Returns a boolean array where two arrays are element-wise equal within a tolerance.

array_equal(a1, a2[, equal_nan])

True if two arrays have the same shape and elements, False otherwise.

array_equiv(a1, a2)

Returns True if input arrays are shape consistent and all elements equal.

greater

less

less_equal

equal

not_equal
