Hi @michael.ford you can certainly construct matrices like that, but I think the best method depends on what is the source data you are trying to populate from?

transpose is good if you already have the transpose of what you want

reshape might make sense if you have the element values in a vector

You can of course just construct it directly from nested clojure vectors with something like (array :my-impl [[1] [2]])

@mikera ok great...thanks very much. love your work by the way 😄
