Is it possible to undo a narrow?
After checking, a narrow does:
if(firstIndex > 0) self->storageOffset += firstIndex*self->stride[dimension];
_  self->size[dimension] = size;_
Could restore the tensor by keeping the original size at dimension, call it s
Then:
self->size[dimension]=s;
self->storageOffset=0;   (or offset before narrowing)
Release 0.5 and on won’t allow for this direct access to the tensor structure,
so I was wondering if there was a way to “un-narrow” without creating a separate structure.
Thanks
