Enum MatrixLayout 

pub enum MatrixLayout {
    RowMajor,
    ColMajor,
    Blocked(Box<MatrixLayout>, usize),
    Packed,
}

Target memory layout for a MatrixTransformer layout conversion.

The Matrix.data buffer is always a flat Vec<f64>; the layout describes how logical element (i, j) is addressed within that buffer. Converting between layouts reorganises the buffer in place and updates Matrix.storage_format accordingly.

Variants

RowMajor

Row-major storage: element (i, j) lives at data[i * cols + j]. This is the canonical layout used throughout the linear-algebra library and the default for sequential row-wise access.

ColMajor

Column-major storage: element (i, j) lives at data[j * rows + i]. Preferred for column-heavy (strided) access patterns.

Blocked(Box<MatrixLayout>, usize)

Cache-friendly blocked (tiled) storage. The matrix is partitioned into block_size x block_size sub-blocks. Blocks themselves are laid out in row-major block order (block row, then block column); within each block the element order follows inner (typically RowMajor).

Edge blocks that fall outside the matrix dimensions contain only the valid elements, so the total buffer length remains rows * cols.

Packed

SIMD-packed storage: each row is zero-padded to a multiple of [SIMD_WIDTH] so that a full SIMD vector load never crosses a row boundary. Element (i, j) lives at data[i * stride + j] where stride = ceil(cols / SIMD_WIDTH) * SIMD_WIDTH; padding slots are 0.0.

Trait Implementations

impl Clone for MatrixLayout

fn clone(&self) -> MatrixLayout

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MatrixLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MatrixLayout

fn eq(&self, other: &MatrixLayout) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
