Struct MatSliceView 

pub struct MatSliceView<'a, 'r, 'c, T> { /* private fields */ }

Matrix slice view

Structure to help creating sub slices of a given matrix when needed. Due to memory structure, slicing creates deep copies, but this function avoids generating them until the last possible moment.

Fields

• data - The faer MatRef (original matrix)
• row_indices - The row indices you want to slice out.
• col_indices - The col indices you want to slice out.

Implementations

impl<'a, 'r, 'c, T> MatSliceView<'a, 'r, 'c, T>

where T: BixverseFloat,

pub fn new( data: MatRef<'a, T>, row_indices: &'r [usize], col_indices: &'c [usize], ) -> MatSliceView<'a, 'r, 'c, T>

Generate a new MatSliceView

This function will panic if you try to select indices larger than the underlying matrix.

Params

• data - The original MatRef from which you want to slice out data
• row_indices - The row indices you want to slice out.
• col_indices - The col indices you want to slice out.

pub fn nrows(&self) -> usize

Return the number of rows

Returns

Number of rows

pub fn ncols(&self) -> usize

Return the number of columns

Returns

Number of columns

pub fn to_owned(&self) -> Mat<T>

Return an owned matrix.

Deep copying cannot be circumvented due to memory accessing at this point. Subsequent matrix algebra needs a continouos view into memory.

Returns

Owned sliced matrix for subsequent usage.

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
