Type Alias Row 

pub type Row<E> = Matrix<DenseRowOwn<E>>;

Heap allocated resizable row vector.

Note

The memory layout of Col is guaranteed to be row-major, meaning that it has a column stride of 1.

Aliased Type

pub struct Row<E> { /* private fields */ }

Implementations

impl<E: Entity> Row<E>

pub fn new() -> Self

Returns an empty row of dimension 0.

pub fn with_capacity(col_capacity: usize) -> Self

Returns a new column vector with 0 columns, with enough capacity to hold a maximum of col_capacity columnss columns without reallocating. If col_capacity is 0, the function will not allocate.

Panics

The function panics if the total capacity in bytes exceeds isize::MAX.

pub fn from_fn(ncols: usize, f: impl FnMut(usize) -> E) -> Self

Returns a new matrix with number of columns ncols, filled with the provided function.

Panics

The function panics if the total capacity in bytes exceeds isize::MAX.

pub fn zeros(ncols: usize) -> Self

where E: ComplexField,

Returns a new matrix with number of columns ncols, filled with zeros.

Panics

The function panics if the total capacity in bytes exceeds isize::MAX.

pub fn nrows(&self) -> usize

Returns the number of rows of the row. This is always equal to 1.

pub fn ncols(&self) -> usize

Returns the number of columns of the row.

pub unsafe fn set_ncols(&mut self, ncols: usize)

Set the dimensions of the matrix.

Safety

The behavior is undefined if any of the following conditions are violated:

• ncols < self.col_capacity().
• The elements that were previously out of bounds but are now in bounds must be initialized.

pub fn as_ptr(&self) -> GroupFor<E, *const E::Unit>

Returns a pointer to the data of the matrix.

pub fn as_ptr_mut(&mut self) -> GroupFor<E, *mut E::Unit>

Returns a mutable pointer to the data of the matrix.

pub fn col_capacity(&self) -> usize

Returns the col capacity, that is, the number of cols that the matrix is able to hold without needing to reallocate, excluding column insertions.

pub fn col_stride(&self) -> isize

Returns the offset between the first elements of two successive columns in the matrix. Always returns 1 since the matrix is column major.

pub fn reserve_exact(&mut self, col_capacity: usize)

Reserves the minimum capacity for col_capacity columns without reallocating. Does nothing if the capacity is already sufficient.

Panics

The function panics if the new total capacity in bytes exceeds isize::MAX.

pub fn resize_with(&mut self, new_ncols: usize, f: impl FnMut(usize) -> E)

Resizes the vector in-place so that the new number of columns is new_ncols. New elements are created with the given function f, so that elements at index i are created by calling f(i).

Returns a reference to a slice over the row.

pub fn as_slice_mut(&mut self) -> GroupFor<E, &mut [E::Unit]>

Safety

The behavior is undefined if any of the following conditions are violated:

• col must be contained in [0, self.ncols()).

pub fn get<ColRange>( &self, col: ColRange, ) -> <RowRef<'_, E> as RowIndex<ColRange>>::Target

where for<'a> RowRef<'a, E>: RowIndex<ColRange>,

Note

The values pointed to by the references are expected to be initialized, even if the pointed-to value is not read, otherwise the behavior is undefined.

• col must be contained in [0, self.ncols()).

where for<'a> RowMut<'a, E>: RowIndex<ColRange>,

Returns mutable references to the element at the given index, or submatrices if col is a range.

Note

The values pointed to by the references are expected to be initialized, even if the pointed-to value is not read, otherwise the behavior is undefined.

The function panics if any of the following conditions are violated:

• col must be contained in [0, self.ncols()).

pub unsafe fn read_unchecked(&self, col: usize) -> E

Reads the value of the element at the given index.

The behavior is undefined if any of the following conditions are violated:

• col < self.ncols().

pub fn read(&self, col: usize) -> E

Reads the value of the element at the given index, with bound checks.

Panics

The function panics if any of the following conditions are violated:

• col < self.ncols().

pub unsafe fn write_unchecked(&mut self, col: usize, value: E)

Writes the value to the element at the given index.
