c This program implements a SIMPLEX algorithm to find the best
c parameters that will fit a function to a set of points.
c PARVERT is a 1-D array that will contain the NPAR-parameters for
c each of the (NPAR+1)-vertex.
c SSD is a 1-D array that contains the sums of std. dev. for each
c one of the (NPAR+1) vertex.
c REFL, EXP, & CONT are 1-D arrays that will contain the NPAR-parameters
c for the reflected, expanded, and contacted vertex respec-
c VAR is another 1-D array that will contain the values of the varia-
c bles (X1,X2,...,XNVAR,Y) for each of the NPOINT-points.
