Hi, yesterday I asked for help in the channel to ask how I could achieve something like Matlab's repmat(): Julia also has a repmat() function, but only for two-dimensional arrays, whereas Matlab's implementation works for as many dimensions as you want. I found about repeat() but didn't understand the docstring (English is not my mother tongue, so that may be an important factor).
When I read the docstring, I was under the impression that repeat() would also only work for two dimensional arrays, which is actually not the case. Thanks to tkelman's help, I could replicate Matlab's repmat() behavior with repeat. Here is repeat()'s docstring: Base.repeat(A, inner = Int[], outer = Int[]) Construct an array by repeating the entries of "A". The i-th element of "inner" specifies the number of times that the individual entries of the i-th dimension of "A" should be repeated. The i-th element of "outer" specifies the number of times that a slice along the i-th dimension of "A" should be repeated. Here is an example of what I wanted to achieve: Let's create an array first: A= diagm([1,2,3,4,5]) Now I want to have this same array repeated along a third dimension. In Matlab, I'd do this: repmat(A,1,1,3) to have a new array with A repeated three times along the third axis. In Julia, this same command doesn't work. So the user has to use repeat(): repeat(A,inner=[1,1,1],outer=[1,1,3]) repeat() is much more useful that Matlab's repmat(), but the docstring is unclear, at least for me. Unfortunately, I don't have, right now, any proposals to correct it. Could maybe an example be added to the docstring? Maybe it could be clearer this way.
