The directory math/deboor +contains the single precision routines. The same routines, edited to provide +double precision, are in the directory "dblprec", which may disappear at some +point in the future if we decide we don't need these. The directory "progs" +contains a number of example programs from the book. + +A number of the routines herein write error messages using Fortran i/o, +violating our convention that numerical routines should not perform i/o. +These routines have been flagged by adding the suffix "_io". These routines +have not been compiled and installed in the library "deboor.a". The most useful +routines either did not do i/o, or have had the i/o removed (e.g., splint.f). + +Note: use the new SPLLSQ for smoothing with splines, instead of L2APPR, if a +uniform knot sequence is desired. Use BSPLN to evaluate the coefficient array +from SPLLSQ. + +Oct 85 Rearranged the order of argument declarations in cwidth.f, dtblok.f, + factrb.f, fcblok.f, sbblok.f, shiftb.f, slvblk.f, subbak.f, subfor.f + to conform with Fortran standard |
