I’ve been scouting the documentation for an “operator.^” which raises each element of a vector to a given scalar power, but haven’t found one. e.g. [1, 2, 3] .^ 2 gives [1, 4, 9]. Am I missing it or is there no such function?

(I’ve seen [this page](http://discourse.mc-stan.org/t/vectorizing-power-function/1516) but it doesn’t answer my question directly.)

No such function, but you can pass a vector to the `square` function.
