Alias for a fixed size array allocated on the stack about array HOT 6 CLOSED

It's already defined in matrix.h as small_matrix.

Thanks, that looks like the right header. I'm looking for the N-dimensional generalization of this - something I can use to define 3D and > arrays.

Gah, I clearly should have read the request more carefully. Now I'm really curious what use you have for a fixed size high dimensional array!

from array.

I was thinking about this a bit. It's probably a good idea to add a fixed_dense_shape type (see #74). This is tricky enough to implement that we should provide a wrapper.

I think adding an alias for array is more questionable though, and not that hard for user code to do with fixed_dense_shape, since it's a one liner with that (replaces your CompactShapeHelper), and doesn't require any big leaps of template programming. It also still requires some decisions from the user (e.g. initialized vs. not).

Thanks, the CompactShapeHelper replacement was most of the code, and I can remove our own implementation of that.

Subsidiary question: do you think matrix_shape and vector_shape from image.h should now also be defined in terms of fixed_dense_shape? This can provide a 'guide' for users that are looking to implement the same.

Thanks again!

matrix_shape has the dense dimension as the second dimension, so it wouldn't be the same thing...
