Struct Larft 

pub struct Larft<TV, TTau = TV, TT = TV> { /* private fields */ }

Typed LARFT triangular-factor operation.

Implementations

impl<TV, TTau, TT> Larft<TV, TTau, TT>

where TV: DataTypeLike, TTau: DataTypeLike, TT: DataTypeLike,

pub fn new(direct: DirectMode, storev: StorevMode, n: usize, k: usize) -> Self

Creates a typed LARFT operation using T’s data type as compute type.

pub const fn with_compute_type(self, compute_type: DataType) -> Self

Sets the compute type passed to the generic cuSOLVER X API.

pub const fn direct(&self) -> DirectMode

Returns the reflector product direction.

pub const fn storev(&self) -> StorevMode

Returns the reflector storage mode.

pub const fn n(&self) -> usize

Returns the reflector order.

pub const fn k(&self) -> usize

Returns the number of elementary reflectors.

pub const fn compute_type(&self) -> DataType

Returns the cuSOLVER compute type.

pub fn workspace_size( &self, ctx: &Context, params: &Params, v: MatrixRef<'_, TV>, tau: VectorRef<'_, TTau>, t: MatrixRef<'_, TT>, ) -> Result<WorkspaceSizes>

Returns the required device and host workspace sizes.

Errors

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

pub fn run( &self, ctx: &Context, params: &Params, args: LarftArgs<'_, TV, TTau, TT>, ) -> Result<()>

Forms the triangular factor in place.

Errors

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

Trait Implementations

impl<TV: Clone, TTau: Clone, TT: Clone> Clone for Larft<TV, TTau, TT>

fn clone(&self) -> Larft<TV, TTau, TT>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<TV: Copy, TTau: Copy, TT: Copy> Copy for Larft<TV, TTau, TT>

impl<TV: Debug, TTau: Debug, TT: Debug> Debug for Larft<TV, TTau, TT>

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

Formats the value using the given formatter.

impl<TV: Eq, TTau: Eq, TT: Eq> Eq for Larft<TV, TTau, TT>

impl<TV: PartialEq, TTau: PartialEq, TT: PartialEq> PartialEq for Larft<TV, TTau, TT>

fn eq(&self, other: &Larft<TV, TTau, TT>) -> 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.
