In the vein of #75 which added stack, it would be really nice if there were a way to easily convert e.g. Vec<Array2<D>> into an Array3<D>. Current I'm doing something like this:
let imshape = data[0].shape()
let mut activation: Array3<f64> = Array3::zeros((n_batch, imshape[0], imshape[1]));
for (i, mm) in data.iter().enumerate() {
activation.slice_mut(s![i, .., ..]).assign(&m);
}
It would be nice to not have to do this manually, it would also be clearer to people who are used to numpy (IMO).
I think this is equivalent to relaxing the restriction that axis in ndarray::stack has to be an existing axis.
