So norm of a periodical function with zero mean value, error of interpolation by piecewise linear functions, error of rectangular quadrature formula and the second modulus of continuity are estimated with sharp constant and stepdoi:10.1016/S1474-6670(17)39661-1Vinogradov, Oleg L....
On spectral accuracy of quadrature formulae based on piecewise polynomial interpolations It is well-known that the trapezoidal rule, while being only second-order accurate in general, improves to spectral accuracy if applied to the integration of a smooth periodic function over an entire period on ...

Although the "pieces" in apiecewisedefinition need not be intervals, a function is not called "piecewiselinear" or "piecewisecontinuous" or "piecewisedifferentiable" unless the pieces are intervals.

In this formula, the signal is constructed by a linear combination of sampled polynomials. Assuming the polynomials pk,k=0,…,K, are fixed, every signal given by (3) is determined uniquely by the set of coefficients {xk}. In contrast to this, we introduce a time index also to these co...
Lagrange interpolation of fuzzy data was first investigated by Lowen [1]. Later, Kaleva [2] avoided the well-known computational troubles associated with crispLagrange interpolation by using linear spline and not-a-knot cubic splineapproximations. If the fuzzy data are not convex, then a technical...
