.help cveval Jun84 "Curfit Package" .ih NAME cveval -- evaluate the fitted function at a single x value .ih SYNOPSIS y = cveval (cv, x) .nf pointer cv # curve descriptor real x # x value .fi .ih ARGUMENTS .ls cv Pointer to the curve descriptor structure. .le .ls x X value at which the curve is to be evaluated. .le .ih DESCRIPTION Evaluate the curve at the specified value of x. CVEVAL is a real function which returns the fitted y value. .ih NOTES It uses the coefficient array stored in the curve descriptor structure. The x values are assumed to lie in the region xmin <= x <= xmax. Checking for out of bounds x values is the responsibility of the user. .ih SEE ALSO cvvector .endhelp
