Hi,
Suppose you have N items, say N = 10.
Now a subset of these items are selected given by a list
A of indices. Lets say that items A = [2,5,7] are
selected. Assume now that you delete some of the items
given by the indices S = [1,4,8]. This means that the
list of indices A must be updated, since items have been
deleted. For this particular case the updated selection
list A becomes A = [1,3,5].
Is there some smart numpy way of doing this index update
of the selected items in A without looping? Typically N
is large.
Best regards,
Mads
