Complete FunctionsA set of Orthonormal Functions is termed complete in the Closed Interval if, forevery piecewise Continuous Function in the interval, the minimum square error
(where denotes the Norm) converges to zero as becomes infinite. Symbolically, a set of functions iscomplete if
where is a Weighting Function and the above is a Lebesgue Integral.See also Bessel's Inequality, Hilbert Space References
