Struct Sytrd 

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

Typed symmetric or Hermitian tridiagonal reduction operation.

Implementations

impl<T> Sytrd<T>

where T: SytrdScalar,

pub const fn new(fill_mode: FillMode, n: usize) -> Self

Creates a typed SYTRD/HETRD operation.

pub const fn fill_mode(&self) -> FillMode

Returns the cuSOLVER fill mode.

pub const fn n(&self) -> usize

Returns the square matrix dimension.

pub fn workspace_len( &self, ctx: &Context, a: MatrixRef<'_, T>, diagonal: VectorRef<'_, T::Real>, off_diagonal: VectorRef<'_, T::Real>, 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: SytrdArgs<'_, T>) -> Result<()>

Reduces the matrix to symmetric or Hermitian tridiagonal form 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 Sytrd<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Copy> Copy for Sytrd<T>

impl<T: Debug> Debug for Sytrd<T>

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

Formats the value using the given formatter.

impl<T: Eq> Eq for Sytrd<T>

impl<T: PartialEq> PartialEq for Sytrd<T>

fn eq(&self, other: &Sytrd<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.
