+NAME
+cvaccum -- accumulate a single data point into the matrix
+.ih
+SYNOPSIS
+include <math/curfit.h>
+
+cvaccum (cv, x, y, weight, wtflag)
+
+.nf
+pointer	cv		# curve descriptor
+real	x		# x value
+real	y		# y value
+real	weight		# weight
+int	wtflag		# type of weighting
+.fi
+.ih
+ARGUMENTS
+.ls cv    
+Pointer to the curve descriptor structure.
+.le
+.ls x   
+X value. Checking for out of bounds x values is the responsibility of the
+user.
+.le
+.ls y    
+Y value.
+.le
+.ls weight   
+Weight assigned to the data point.
+.le
+.ls wtflag
+Type of weighting. The options are WTS_USER, WTS_UNIFORM or WTS_SPACING.
+If wtflag equals WTS_USER the weight for each point is supplied by the user.
+If wtflag is either WTS_UNIFORM or WTS_SPACING the routine sets weight
+to one.
+.le
+.ih
+DESCRIPTION
+Calculate the non-zero basis functions for the given value of x.
+Compute the contribution of the data point to the normal equations and
+sum into the appropriate arrays and vectors.
+.ih
+NOTES
+The WTS_SPACING option cannot be used with CVACCUM. Weights will be set
+to 1.
