Is there a iterative version of select? #1108
Description
I'd like to iterate an Array along one axis over a set of selected indices. However I am not able to find such a method.
I notice that the fn select(&self, axis, &[Idx]) returns a copy, which is inefficient for read only iterative operation.
Is there such a method fulfill this purpose?
e.g., if there is hypothetical method, I'd like to use it in the way
for s in someArray.selected_indices(Axis(0), &[1,2,4,8,16]){
//some read only operation to s
}
