| Abstract: | To compute approximately an integral where φm( ) is cardinal B-spline, we used composite rectangular rule. We proved that, on the “quasi uniform” mesh, the used formula has, conditionally speaking, algebraic degree of exactness m−1. Under additional assumptions, algebraic degree of exactness is m. |
