Struct Orgbr 

pub struct Orgbr<T> { /* private fields */ }

Typed operation that forms explicit bidiagonalization factors.

Implementations

impl<T> Orgbr<T>

where T: OrgbrScalar,

pub const fn new( side: SideMode, rows: usize, cols: usize, reflectors: usize, ) -> Self

Creates a typed ORGBR/UNGBR operation.

pub const fn side(&self) -> SideMode

Returns whether to form Q or P.

pub const fn rows(&self) -> usize

Returns the output matrix row count.

pub const fn cols(&self) -> usize

Returns the output matrix column count.

pub const fn reflectors(&self) -> usize

Returns the number of elementary reflectors.

pub fn workspace_len( &self, ctx: &Context, a: MatrixRef<'_, T>, tau: VectorRef<'_, T>, ) -> Result<usize>

Returns the required legacy workspace length in elements.

Errors

Returns an error if inputs are invalid or if cuSOLVER cannot report the workspace length.

pub fn run(&self, ctx: &Context, args: OrgbrArgs<'_, T>) -> Result<()>

Forms the explicit bidiagonalization factor matrix in place.

Errors

Returns an error if inputs or workspace are invalid, or if cuSOLVER reports a failure.

Trait Implementations

impl<T: Clone> Clone for Orgbr<T>

fn clone(&self) -> Orgbr<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Copy> Copy for Orgbr<T>

impl<T: Debug> Debug for Orgbr<T>

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

Formats the value using the given formatter.

impl<T: Eq> Eq for Orgbr<T>

impl<T: PartialEq> PartialEq for Orgbr<T>

fn eq(&self, other: &Orgbr<T>) -> 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.
