Enum HtNode3DComplex 

pub enum HtNode3DComplex {
    Leaf {
        dim: usize,
        frame_re: Mat<f64>,
        frame_im: Mat<f64>,
    },
    Interior {
        left: usize,
        right: usize,
        transfer: Vec<f64>,
        ranks: [usize; 3],
    },
}

A node in the complex 3D HT dimension tree.

Leaf frames are complex (split real/imaginary storage); transfer tensors remain real because FFT only acts on leaves and does not change the rank structure.

Variants

Leaf

Leaf: complex frame stored as separate real and imaginary matrices.

Fields

dim: usize

Dimension index (0 = x1, 1 = x2, 2 = x3).

frame_re: Mat<f64>

Real part of the leaf frame, shape (n, k).

frame_im: Mat<f64>

Imaginary part of the leaf frame, shape (n, k).

Interior

Interior: real transfer tensor (identical layout to HtNode3D::Interior).

Fields

left: usize

Index of the left child node.

right: usize

Index of the right child node.

transfer: Vec<f64>

Flattened transfer tensor of size k_t * k_left * k_right.

ranks: [usize; 3]

Rank triple [k_t, k_left, k_right].
