diagv

Matrix product with a diagonal matrix

Computes faster the product of a diagonal matrix times a full matrix.

diagv(v, M)

`v`	A numeric vector specifying the elements on the diagonal of a matrix.
`M`	A numeric matrix compatible with the product D_v M.

Computes N = D_v M where D_v is diagonal avoiding the diag operator.

A matrix N.

v <- 1:1000
M <- matrix(runif(3000), 1000, 3)
dim(diagv(v, M))
