Detailed Description

template<Expression Source>
class tannic::expression::Squeeze< Source >

Expression template for removing singleton dimensions from a tensor.

Template Parameters

Source

The expression or tensor type being squeezed.

The Squeeze view removes dimensions of size 1 from the shape of a tensor. This changes only the tensor metadata (shape and strides), not the underlying storage.

Example:

Tensor X(float32, {1, 3, 1});
auto Y = squeeze(X); // shape becomes (3)

Constructor & Destructor Documentation

Squeeze()

template<Expression Source>

constexpr tannic::expression::Squeeze< Source >::Squeeze ( typename Trait< Source >::Reference  source )

inlineconstexpr

Construct a squeezed view of the source tensor.

Parameters

source

Reference to the source expression or tensor.

This constructor removes all dimensions of size 1 from the source shape. Strides corresponding to those singleton dimensions are also removed.

Member Function Documentation

dtype()

template<Expression Source>

constexpr type tannic::expression::Squeeze< Source >::dtype ( ) const

inlineconstexpr

Returns

The runtime data type of the tensor elements.

This is forwarded directly from the source expression. Squeezing does not alter the tensor’s dtype.

forward()

template<Expression Source>

Tensor tannic::expression::Squeeze< Source >::forward

offset()

template<Expression Source>

std::ptrdiff_t tannic::expression::Squeeze< Source >::offset ( ) const

inline

Returns

The byte offset of the squeezed tensor from the start of storage.

This is forwarded from the source tensor since squeezing does not change the starting position of the data.

shape()

template<Expression Source>

constexpr Shape const & tannic::expression::Squeeze< Source >::shape ( ) const

inlineconstexpr

Returns

The shape of the squeezed tensor.

Calculation:

• Copies the source shape.
• Removes all dimensions of size 1.

Example:

• Source shape: (1, 3, 1) → Squeezed shape: (3)

strides()

template<Expression Source>

constexpr Strides const & tannic::expression::Squeeze< Source >::strides ( ) const

inlineconstexpr

Returns

The strides of the squeezed tensor.

Calculation:

• Copies the source strides.
• Removes strides corresponding to dimensions of size 1.

Example:

• Source strides: (3, 1, 1) with shape (1, 3, 1)
• Result after squeeze: (1) with shape (3)
