dhprod: Element-wise (Hadamard) product

In bigalgebra: 'BLAS' and 'LAPACK' Routines for Native R Matrices and 'big.matrix' Objects

Element-wise (Hadamard) product

Description

Computes Z := X \circ Y. When 'Z' is missing it is allocated automatically.

Usage

dhprod(N = NULL, X, INCX = 1L, Y, INCY = 1L, Z, INCZ = 1L)

Arguments

N	Optional integer giving the number of elements. Defaults to 'length(X)'.
X	Double-precision vector, matrix or ['bigmemory::big.matrix'] input.
INCX	Integer stride for traversing 'X'.
Y	Double-precision object updated in place.
INCY	Integer stride for traversing 'Y'.
Z	Optional output container receiving the product.
INCZ	Integer stride for 'Z'.

Value

The updated object 'Z'.

Examples

dhprod(X = 1:4, Y = rep(2, 4))
