rand_like([rng=default_rng()], x, [element_type=eltype(x)], [dims=size(x)])

Create an array with the given element type and size, based upon the given source array x. All element of the new array will be set to a random value. The last two arguments are both optional, defaulting to the given array's eltype and size. The dimensions may be specified as an integer or as a tuple argument.

The default random number generator is used, unless a custom one is passed in explicitly as the first argument.
