A spring function of the magnetic force can be approximated by a simple function, F(x)=A[D/(B+x)]^P + C, where x is the pole-gap distance. It has been established experimentally in our previous study that the constants B and C greatly increase the approximation accuracy of the formula, although they have never been used conventionally. However, the procedure to obtain B and C together with A, D and P is rather complicated. The present study is devoted to the revision of the algorithm and the program. The performance of the method is examined by numerical examples to verify the accuracy of the function approximation as well as the constant identification. The influence of the random noise superimposed on the data and the ability to identify some special test data are examined. A numerical discussion of the strongly nonlinear spring property which was found previously is also presented. A listing of the program is accompanied by its instruction manual.
