In BigDataStatMeth: Scalable Statistical Computing with HDF5-Backed Matrices

Matrix–scalar weighted product

Description

Multiplies a numeric matrix A by a scalar weight w, returning w * A. The input must be a base R numeric matrix (or convertible to one).

Usage

bdScalarwproduct(A, w)

Arguments

A	Numeric matrix (or object convertible to a dense numeric matrix).
w	Numeric scalar weight.

Value

A numeric matrix with the same dimensions as A.

Examples

set.seed(1234)
n <- 5; p <- 3
X <- matrix(rnorm(n * p), n, p)
w <- 0.75
