struct ExprMVNode

Defined in src/lib/ncarray/expression/mvnode.hh:83

Inherits: ExpressionTag

A multi-view array expression builder.

ExprMVNode is a host-only expression builder. It has no restrictions on the number, or type of arrays (e.g. operands including views from multiple arrays are supported).

ExprMVNode

inline

template<AnyExpressionOrScalar Node> inline ExprMVNode(const Node & node)

Defined in src/lib/ncarray/expression/mvnode.hh:109

A converting constructor is provided for ergonomics.

This mostly allows inplace operators to work without end-users needing to think or know about the underlying expression tape/tree/node/etc….
