Struct VerticallyStridedRowIndexMap

pub struct VerticallyStridedRowIndexMap { /* private fields */ }

A vertical row-mapping strategy that selects every stride-th row from an inner matrix, starting at a fixed offset.

This enables vertical striding like selecting rows: offset, offset + stride, etc.

Implementations

impl VerticallyStridedRowIndexMap

pub fn new_view<T: Send + Sync + Clone, Inner: Matrix<T>>( inner: Inner, stride: usize, offset: usize, ) -> VerticallyStridedMatrixView<Inner>

Create a new vertically strided view over a matrix.

This selects rows in the inner matrix starting from offset, and then every stride rows after.

Arguments

• inner: The inner matrix to view.
• stride: The number of rows between each selected row.
• offset: The initial row to start from.
