NAME
cvreject -- reject a single data point from the data set to be fit
.ih
SYNOPSIS
cvreject (cv, x, y, weight)
.nf
pointer cv # curve descriptor
real x # x value
real y # y value
real weight # weight value
.fi

ARGUMENTS
.ls cv
Pointer to the curve descriptor structure.
.le
.ls x
X value.

DESCRIPTION
CVREJECT removes an individul data point from the data set.
The non-zero basis functions for each x are calculated. The contribution
of each x to the normal equations is computed and subtracted from the
appropriate arrays and vectors.
An array of points can be removed from the fit by repeated calls to CVREJECT
followed by a single call to CVSOLVE to calculate a new set of coefficients.
