Detailed Description

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

Creates a real-valued view of complex tensor data.

Template Parameters

Source

Complex tensor type

Transformation Rules:

• type: complex64 → float32, complex128 → float64
• Shape: [...,N] → [...,N,2] (adds dimension for components)
• Memory: Maintains same storage with adjusted strides

Requirements:

• Input must be complex64 or complex128
• Must have stride 1 in last dimension (contiguous complex pairs)

Example:

// complex64 input with shape [2]
Tensor cplx = {1+2i, 3+4i};
 
// float32 output with shape [2,2] 
Tensor real_view = realify(cplx);
// real_view = [[1, 2],  // real, imag components
//              [3, 4]]

Member Function Documentation

dtype()

template<Expression Source>

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

inlineconstexpr

Returns the real dtype of the view.

Returns

float32 if source was complex64, float64 if complex128

Transformation Rule:

complex64 → float32
complex128 → float64

forward()

template<Expression Source>

Tensor Realification::forward

offset()

template<Expression Source>

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

inline

shape()

template<Expression Source>

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

inlineconstexpr

Returns the shape of the real view.

Returns

Shape with last dimension expanded to 2

Transformation Rule:

[...,N] → [...,N,2]

Example:

Tensor cplx({2});       // [a+bi, c+di]
auto real = realify(cplx);
real.shape();           // Returns [2,2]

strides()

template<Expression Source>

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

inlineconstexpr

Returns the strides of the real view.

Returns

Strides adjusted for component access

Transformation Rules:

• Last stride becomes 1 (contiguous components)
• Penultimate stride doubles (distance between complex numbers)
