int conj_op(const int & a)

source edit

Python wrappers

pylucid.ops.conjfunction

Return the element-wise complex conjugate of a tensor.

For C64 input, produces a fresh C64 tensor whose imaginary part is negated. For any real dtype the operator is a no-op (the conjugate of a real number equals itself) and the backend short-circuits the dispatch.

Math

y_k = \overline{z_k}

real_op, imag_op, complex_op

Parameters

aTensorImplPtr

Input tensor. May be any dtype; only C64 produces a non-trivial transformation.

Returns

TensorImplPtr

Tensor with the same shape, dtype, and device as a.

Notes

Backward is performed at the Python autograd layer as another conj on the incoming gradient, consistent with the Wirtinger calculus convention adopted by the reference framework.
