Özet

In this paper quadratic and quartic B-splines were used for reconstructionof an approximating function, where the integral values of successive subintervals wereused instead of function values at the knots. After introducing integro quadratic andquartic interpolation a comparison was done between them through presenting numericalexamples. The interpolation errors for quadratic and quartic integro interpolation arestudied. Numerical results illustrate the efficiency and effectiveness of the new interpo-lation methods.
