Expand description

Result of preparing a tensor contraction.

Contains all the information needed to perform the contraction:

Which axes to contract from each tensor
The resulting indices and dimensions after contraction

Fields§

§axes_a: Vec<usize>

Axes to contract from the first tensor (positions in indices_a).

§axes_b: Vec<usize>

Axes to contract from the second tensor (positions in indices_b).

§result_indices: Vec

Indices of the result tensor (non-contracted indices from both tensors).

§result_dims: Vec<usize>

Dimensions of the result tensor.
