Unfortunately, the ravel/reshape methods seem to not be quite worked out properly yet. Basically (and as expected) the ravel method doesn't work anymore on fortran-strided arrays. But since fortran-strided arrays happen *all-the-time* (e.g. after a transpose operation), things get confusing fast.

One question: was the issue in my example code where fortran-strided arrays couldn't be reshaped at all a feature or a bug in the reshape method? It's now a feature. Reshape will only work if it can produce a view of

I'm sure there are cases where a view is technically feasible. The simple rules are: 1) If you are only adding or deleting ones from the shape, then it always succeeds. 2) If you aren't actually changing the shape it always succeeds (a -1 present means you are changing the shape) Other than that it only succeeds if you are reshaping a C-contiguous array using C-ordering or you are reshaping a Fortran-contiguous array using Fortran-ordering. -Travis
