dsqrt: Element-wise square root

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

Element-wise square root

Description

Applies the square root to each entry of 'X' in place, supporting both base R and ['bigmemory::big.matrix'] inputs.

Usage

dsqrt(N = NULL, X, INCX = 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'.

Value

Invisibly returns the modified object 'X'.

Examples

vals <- matrix(c(1, 4, 9, 16), 2)
dsqrt(X = vals)
vals
