Abstract
We construct and analyze discontinuous interpolating splines for the approximation of discontinuous functions. We develop an algorithm to estimate the discontinuous function whose unknown discontinuities lie on the lines parallel to the coordinate axes, by approximating it by the discontinuous interpolating spline. We also develop an algorithm to find the discontinuities of the discontinuous function on the basis of the concept of ε-continuity of functions of two variables and present the examples.
