Abstract:
This algorithm is one of the methods that use spline functions for interpolation. In the context of general interpolation the coefficients are calculated using the values of the function and function’s derivatives in the knots. Compared with another known algorithm, in this case is not necessary to perform the signal extension. But appear another problem: how to calculate the values for the derived function. Three methods are presented to resolve this. All the methods were applied for several input signals. From the practical results were made some conclusions.
