Or ... if you mean "simpler" as in "less to type", you can define your own binary operator by enclosing it in "%" signs, and the assign any of the previously proposed solutions, e.g.
y = matrix(cbind(c(0, 0.5, 1),c(0, 0.5, 1)),ncol=2)
z = matrix(c(12, -6),ncol=2)
'%.*%' <- function(a,b) {a * rep(b, each=3)}
y %.*% z
[,1] [,2]
[1,] 0 0
[2,] 6 -3
[3,] 12 -6
