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
#> [,1] [,2]
#> [1,] 1 3
#> [2,] 2 4
