Struct Submatrix

pub struct Submatrix<'a, V, T>
where
    V: 'a + AsPointerToSlice<T>,
{ /* private fields */ }

Immutable view on a matrix that stores elements of type T.

This view is designed to work with various underlying representations of the matrix, as described by AsPointerToSlice.

Implementations

where V: 'a + AsPointerToSlice<T>,

pub fn submatrix(self, rows: Range<usize>, cols: Range<usize>) -> Self

pub fn restrict_rows(self, rows: Range<usize>) -> Self

pub fn into_at(self, i: usize, j: usize) -> &'a T

pub fn at<'b>(&'b self, i: usize, j: usize) -> &'b T

pub fn restrict_cols(self, cols: Range<usize>) -> Self

pub fn row_iter(self) -> impl 'a + Clone + ExactSizeIterator<Item = &'a [T]>

pub fn col_iter( self, ) -> impl 'a + Clone + ExactSizeIterator<Item = Column<'a, V, T>>

pub fn into_row_at(self, i: usize) -> &'a [T]

pub fn row_at<'b>(&'b self, i: usize) -> &'b [T]

pub fn into_col_at(self, j: usize) -> Column<'a, V, T>

pub fn col_at<'b>(&'b self, j: usize) -> Column<'b, V, T>

pub fn row_count(&self) -> usize

impl<'a, T> Submatrix<'a, AsFirstElement<T>, T>

pub fn from_1d(data: &'a [T], row_count: usize, col_count: usize) -> Self

Creates a view on the given data slice, interpreting it as a matrix of given shape. Assumes row-major order, i.e. contigous subslices of data will be the rows of the resulting matrix.

pub fn from_ndarray<S>(data: &'a ArrayBase<S, Ix2>) -> Self

where S: DataMut<Elem = T>,

Available on crate feature ndarray only.

impl<'a, V: AsPointerToSlice<T> + Deref<Target = [T]>, T> Submatrix<'a, V, T>

pub fn from_2d(data: &'a [V]) -> Self

Interprets the given slice of slices as a matrix, by using the elements of the outer slice as the rows of the matrix.

Trait Implementations
