Conjugates the given tensor about the target tensor.

This method computes a target tensor conjugated by another tensor. Here conjugate is used in the sense of conjugating by a matrix, i.a. A conjugated about B is $$A B A^\dagger$$ where $$\dagger$$ represents the conjugate transpose.

Abstractly this compute $$A \cdot B \cdot A^\dagger$$ where A and B are multi-dimensional arrays, and instead of matrix multiplication $$\cdot$$ is a contraction between the given indices (indices for first $$\cdot$$, conj_indices for second $$\cdot$$).

More specifically this computes $\sum tensor_{i0,...,i{r-1},j0,...,j{r-1} } * target_{k0,...,k{r-1},l0,...,l{r-1} } * tensor_{m0,...,m{r-1},n0,...,n{r-1} }^*$

where the sum is over indices where $$j_s$$ = $$k_s$$ and $$s$$ is in indices and $$l_s$$ = $$m_s$$ and s is in conj_indices.

tensor The tensor that will be conjugated about the target tensor.
target The tensor that will receive the conjugation.
indices The indices which will be contracted between the tensor and target.
conj_indices The indices which will be contracted between the complex conjugate of the tensor and the target. If this is None, then these will be the values in indices plus half the number of dimensions of the target (ndim). This is the most common case and corresponds to the case where the target is an operator on a n-dimensional tensor product space (here n would be ndim).
buffer A buffer to store partial results in. If not specified or None, a new buffer is used.
out The buffer to store the results in. If not specified or None, a new buffer is used. Must have the same shape as target.

The result the conjugation.
