Though I can't say I've thoroughly tested this, the intended functionality is that you provide a nested structure and you specify the shape of the units with the first argument. For example, if I provide a 8x10x2 nested structure that's intended to be a complex matrix, I would put an (int-array [2]) in the first argument and the result should be an 8x10 data structure with 2x1 dimensional units. I intended that an exception be thrown if the unit shape doesn't match the structure of the last few dimensions. > > 2) Shapes and indices are all int, rather than long.

I could theoretically back the data structures with more than one array, but the maximum index is defined by the int, I think. > PS: I am using PersistentMatrix rather successfully in reading data > from HDF5 files! Exciting! I was also taking a look at the NetCDF format. It looks interesting as well. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
