Function svd_with 

pub fn svd_with<T>(
    t: &TensorDynLen,
    left_inds: &[DynIndex],
    options: &SvdOptions,
) -> Result<(TensorDynLen, TensorDynLen, TensorDynLen), SvdError>

Compute SVD decomposition of a tensor with arbitrary rank, returning (U, S, V).

This function allows per-call control of the truncation tolerance via SvdOptions. If options.rtol is None, uses the global default rtol.
