Detailed Description

template<typename Left, typename Right, typename Result>
class TiledArray::expressions::MultEngine< Left, Right, Result >

Multiplication expression engine.

This implements any expression encoded with the multiplication operator. This includes Hadamard product, e.g.

(c("i,j")=)a("i,j")*b("i,j")

, and pure contractions, e.g.

(c("i,j")=)a("i,k")*b("k,j")

.
