    Notes: Abstract We establish a result related to a theorem of de Boor and Jia [1]. Their theorem, in turn, corrected and extended a result of Fix and Strang [5] concerning controlled approximation. In our result, the approximating functions are not required to have compact support, but satisfy instead conditions on their behavior at ∞. Our theorem includes some recent results of Jackson [6] and is closely related to the work of Buhmann [2].
