% private_STBEG -- Sets some initial parameters for STEPIT. Somewhat archaic and leftover from matlab, a large number of its duties have been %
% dropped by the current author, being implented elsewhere or by easier ways. Still, I retain the original structure of the program %
% for clarity's sake. %
% %
% %
% INPUT QUANTITIES-- FUNK,X,XMAX,XMIN,DELTX,DELMIN,NV,NTRACE,MATRX,MASK,NFMAX,NFLAT,KW %
% %
% OUTPUT QUANTITIES-- NSSW,NACTIVE,NF,KFLAG,NOREP AND SOMETIMES X,XMAX,XMIN,DELTX,DELMIN %
% %
% DOUBLE PRECISION-- X,XMAX,XMIN,DELTX,DELMIN,ERR,FOBJ,DX,XS,DLX,HUGE,DELDF,RZERO,UNITR,RTEN,RELACC,XPLUS,FSAVE %
% %
% INTEGER-- J,JUMP,JVARY,KERFL,KFLAG,KTYPE,KW,MASK,MATRX,NACTIV,NF,NFLAT,NFMAX,NOREP,NSSW,NTRACE,NV,NVMAX,NXTRA %
