int logical_and_op(const int & a, const int & b)

source edit

Python wrappers

pylucid.ops.logical_andfunction

Elementwise logical AND: $y_i = [a_i \ne 0] \land [b_i \ne 0]$ .

Composite over not_equal_op (to coerce each operand to a bool mask) + bitwise_and_op. Not differentiable — the output is integral and bitwise_* has no backward.

Math

y_i = \mathbb{1}\!\left[ a_i \ne 0 \right] \cdot \mathbb{1}\!\left[ b_i \ne 0 \right]

bitwise_and_op — bit-level variant on integer inputs.

Parameters

a, bTensorImplPtr

Operands of broadcastable shapes and arbitrary numeric dtype.

Returns

TensorImplPtr

Bool tensor on the broadcast shape of a and b.
