Hi Konrad, In writing these functions, I was trying to blend the worlds of lispy data structure building and more familiar matrix indexing.
I wanted to be able to treat matrices like elements of a list that could be consed/conjed together to build up data abstractions. This is necessary to keep in spirit with clojure's other data structures. Say that you're dealing with a structure of x dimensions. In this frame, imagine that you have a list of x-1 dimensional objects in a list that is as long as the xth dimension. You can cons up these things that are n-1 in dimensionality and use nth as a linear index for these n-1 dimensional structures. In other words, nth should be used when operating on the outer-most/last dimension, whereas the index method is intended to be used when you're treating the data structure as a whole. Let me know if my explanation isn't clear. > -> #<PersistentMatrix > [[1, 2] > [3, 4] > [5, 6]]> Also, the printing isn't correct yet. The rows should be switched with the columns, but that didn't seem trivial, so I have postponed it for a while. > (.index m (int-array [1])) > -> 2 This shouldn't happen. This should actually raise an exception. I intended index only to be used when you specify an index for all of the dimensions. I have a project push well into june, but after that I will be developing the library more actively. Please, keep the questions/comments coming! -Adler --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
