Parameters

cs	Tensor streams.
fargs	Forwarded functor constructor arguments.

Member Function Documentation

template<class F, class... Cs>

constexpr size_t lin::internal::StreamElementWiseOperator< F, Cs >::rows ( ) const

inline

Returns

Number of rows in the tensor.

template<class F, class... Cs>

constexpr size_t lin::internal::StreamElementWiseOperator< F, Cs >::cols ( ) const

inline

Returns

Number of columns in the tensor.

template<class F, class... Cs>

constexpr Traits::elem_t lin::internal::StreamElementWiseOperator< F, Cs >::operator() ( size_t  i, size_t  j  ) const

inline

Lazily evaluates the requested tensor element.

Parameters

i	Row index.
j	Column index.

Returns

Resulting value of the tensor element.

You may want to consider for the creation of a value backed type to reduce overhead.

internal::Stream::eval

template<class F, class... Cs>

constexpr Traits::elem_t lin::internal::StreamElementWiseOperator< F, Cs >::operator() ( size_t  i ) const

inline

Lazily evaluates the requested tensor element.

Parameters

i

Index.

Returns

Resulting value of the tensor element.

Element access proceeds as if all the elements of the tensor stream were flattened into an array in row major order.

You may want to consider for the creation of a value backed type to reduce overhead.
