Akima Spline Interpolation

Function: - Akima Spline Interpolation 3

From a general point of view Akima interpolations for this function is successful. This function has the ability to increase the oscillation frequency by increasing x. Still the interpolation graph is good and follows the function well. The max and min functional values are -1 and 1 which are not equal to the interpolation values. To get better results the number fitted nodes is increased from 100 to 200.

Graph 24. Function: - Akima Spline Interpolation. The function maximum and minimum are 1 and -1. Akima interpolation gives us a good result but does not completely follow the maximums and minimums. To produce a better fit increase the number of fitted nodes by at least twice.
