Struct SwapOptions

Source

pub struct SwapOptions {
    pub max_rank: Option<usize>,
    pub rtol: Option<f64>,
}

Expand description

Options for site index swap (truncation during SVD).

When max_rank or rtol are set, the swap may introduce approximation error by truncating bond dimension. Default (both None) allows rank growth to preserve the tensor exactly.

Fields§

§max_rank: Option<usize>

Maximum bond dimension after each SVD (None = no limit).

§rtol: Option<f64>

Relative tolerance for singular value truncation (None = no truncation).
