fn mul_quat_partial(
x_bmhr: Tensor<4>,
f_bhj4: Tensor<4>,
tail_bh: Tensor<2>,
rope_width: usize,
) -> Tensor<4>Expand description
Left-multiply the first rope_width state-rank entries of x by the (not
necessarily unit) quaternion f per block, and scale the pass-through
entries by the real scalar tail — the quaternion analogue of
mul_complex_partial.
