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
.ih
ARGUMENTS
.ls cv    
Pointer to the curve descriptor structure.
.le
.ls x   
X value.
.le
.ls y
Y value.
.le
.ls weight
The weight 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.
