Section titled “ExprMVNode”
#include <mvnode.hh>
template<class MemTag = DevTag>
struct ExprMVNode

Defined in src/lib/ncarray/expression/mvnode.hh:99

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).
