Function Usage

Overloads the () operator. The internal implementation is to call the Crd2Idx API to convert multidimensional coordinates to a memory location index based on the layout.

Prototype

template <typename CoordType>
__aicore__ inline constexpr auto operator()(const CoordType& coord) const {}

Parameters

Parameter	Input/Output	Description
coord	Input	Coord structure type, which is used to indicate the coordinates of a tensor in different dimensions.

Returns

Returns the index value converted based on the coordinate information.

Restrictions

None

Examples

...
auto layout = AscendC::MakeLayout(shape, stride);
auto index = layout(coord);
