      r"""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_{i_0,...,i_{r-1},j_0,...,j_{r-1}}
          * target_{k_0,...,k_{r-1},l_0,...,l_{r-1}
          * tensor_{m_0,...,m_{r-1},n_0,...,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`.
  
      Args:
          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.
  
      Returns:
          The result the conjugation.
