Hello!

Suppose I have an array of different values, `Result`.

Usually one would write; `clamp!(Result,LowerLimit,HigherLimit)`. Is there a way to make it “one-sided” such that I only specify a lower limit?

Kind regards

There’s an example in the docs:

```julia-repl
julia> clamp.((-4:4)', 0, Inf)
 1×9 Matrix{Float64}:
   0.0 0.0 0.0 0.0 0.0 1.0 2.0 3.0 4.0

```

Thanks! Had not realized it was this simple 🙂 I was trying “nothing” instead of Inf

Kind regards

The right way to do this is not to use `clamp`, but `max`:

```julia
max.((-4:4)', 0)

```
