…s not fully match the one described in the paper: Spline-based Nonlinear Biplots; the code includes a penalty term (consistent with the FORTRAN implementation), which is not in the paper.
…before merging. The folder is added to .Rbuildignore so it does not affect the package.
…its alignment with the Fortran implementation.
//Optimize alfunc by computing Z directly from BVEC and combining loops

//- Eliminated intermediate B matrix creation by computing Z = M %*% B directly from BVEC vector
//- Combined three separate loops (exind, prediction, loss calculation) into single pass
//- Removed fortran-unused utility functions matm() and exind()
//- Reduces memory allocations and improves cache locality
//- Maintains identical mathematical behavior with better performance
Replacement  Loss function and Nelder-Mead based on FORTRAN with new version based on Rcpp (KMbranch)
refactor biplot.spline.axis documentation and remove unused Rd file
