Hi,
It is better to use sweep() for these kinds of problems, see ?sweep
y <- matrix(cbind(c(0, 0.5, 1),c(0, 0.5, 1)),ncol=2)
z <- matrix(c(12, -6),ncol=2)
sweep(y, 2, z, "*")
Best,
Denes

In matlab I would do this
y .* x
I would get this in matlab
ans
0 -0
6 -3
12 -6
What is the equivalent in R?
One way of doing this could be:
y * rep(z,1,each=nrow(y))
