Struct Matrix

pub struct Matrix<C>
where
    C: CubeType,
{ /* private fields */ }

A matrix represent a 2D grid of numbers.

They can either be in a row major or a column major format.

Implementations

impl<C> Matrix<C>

where C: CubePrimitive,

pub unsafe fn uninitialized( ident: MatrixIdent, m: u32, n: u32, k: u32, layout: MatrixLayout, ) -> Matrix<C>

Create a new uninitialized matrix that is going to be used in the matrix-multiply and accumulate function.

Safety

Must be initialized with load or fill before use. Using it without initialization is undefined behaviour on CUDA, and completely invalid on Vulkan.

You have to declare the shape used for the execution. The shape of the current matrix is determined using the MatrixIdent.

• MatrixIdent::A Shape => (M, K)
• MatrixIdent::B Shape => (K, N)
• MatrixIdent::Accumulator Shape => (M, N)

Not all shapes are supported, and the permitted shapes depend on the element type.

Refer to nvidia documentation.

pub fn from_value( ident: MatrixIdent, m: u32, n: u32, k: u32, layout: MatrixLayout, value: C, ) -> Matrix<C>

Create a new matrix that is going to be used in the matrix-multiply and accumulate function and is filled with value.

You have to declare the shape used for the execution. The shape of the current matrix is determined using the MatrixIdent.

• MatrixIdent::A Shape => (M, K)
• MatrixIdent::B Shape => (K, N)
• MatrixIdent::Accumulator Shape => (M, N)

Not all shapes are supported, and the permitted shapes depend on the element type.

Refer to nvidia documentation.

pub fn from_slice( ident: MatrixIdent, m: u32, n: u32, k: u32, layout: MatrixLayout, value: &Slice<C>, stride: u32, ) -> Matrix<C>

Create a new matrix that is going to be used in the matrix-multiply and accumulate function and is loaded from value with stride.

You have to declare the shape used for the execution. The shape of the current matrix is determined using the MatrixIdent.

• MatrixIdent::A Shape => (M, K)
• MatrixIdent::B Shape => (K, N)
• MatrixIdent::Accumulator Shape => (M, N)

Not all shapes are supported, and the permitted shapes depend on the element type.

pub fn __expand_uninitialized( scope: &mut Scope, ident: MatrixIdent, m: ExpandElementTyped<u32>, n: ExpandElementTyped<u32>, k: ExpandElementTyped<u32>, layout: MatrixLayout, ) -> MatrixExpand<C>

pub fn __expand_from_value( scope: &mut Scope, ident: MatrixIdent, m: ExpandElementTyped<u32>, n: ExpandElementTyped<u32>, k: ExpandElementTyped<u32>, layout: MatrixLayout, value: ExpandElementTyped<C>, ) -> MatrixExpand<C>

pub fn __expand_from_slice( scope: &mut Scope, ident: MatrixIdent, m: ExpandElementTyped<u32>, n: ExpandElementTyped<u32>, k: ExpandElementTyped<u32>, layout: MatrixLayout, value: SliceExpand<C, ReadOnly>, stride: ExpandElementTyped<u32>, ) -> MatrixExpand<C>

Trait Implementations

impl<C> Clone for Matrix<C>

where C: Clone + CubeType,

fn clone(&self) -> Matrix<C>
