Abstract
A result of Strang and Fix states that if the order of controlled approximation from a collection of locally supported elements is , then there is a linear combination of those elements and their translates such that any polynomial of degree less than can be reproduced by and its translates. This paper gives a counterexample to their result.Keywords
