How to perform element-wise square root of a vector in Julia?

Question

I need to perform the square root of an array in Julia but it seems sqrt() function just performs square roots on scalars and square matrices. Is there any simple compact way to do it without using loops?

Answer 1

The documentation https://docs.julialang.org/en/v1/manual/arrays/#Array-and-Vectorized-Operators-and-Functions-1 tells you that to apply any function elementwise over an array, use the dot-broadcasting syntax:

sqrt.(x)
.√(x)
