Suggest you look at using R with a package.

Package earth should help. See also below attachment. Best wishes, David Booth

Please remember that R is open source. Thus you could examine the R code which may be helpful to you in programming the procedure in question. One doesn't have to completely reinvent the wheel Everytime. Best, D. Booth
