in	The several elements to store
i	The position at which to start. This will be aligned from the beginning (multiple of the vector size).

Template Parameters

V	The vectorization mode to use

◆ swap()

template<typename T, typename ST, order SO, size_t... Dims>

void etl::fast_matrix_impl< T, ST, SO, Dims >::swap ( fast_matrix_impl< T, ST, SO, Dims > & other )

inline

Swap the contents of the matrix with another matrix.

Parameters

other The other matrix

◆ visit()

template<typename T, typename ST, order SO, size_t... Dims>

void etl::fast_matrix_impl< T, ST, SO, Dims >::visit ( [[maybe_unused] ] const detail::evaluator_visitor & visitor ) const

inline

Apply the given visitor to this expression and its descendants.

Parameters

visitor The visitor to apply
