Purpose

E01BFF Interpolated values, interpolant computed by E01BEF, function only, one variable

Synopsis

[pf,ifail] = e01bff(x,f,d,px<,ifail>)

Description

 
 This routine evaluates a piecewise cubic Hermite interpolant, as 
 computed by E01BEF, at the points PX(i), for i=1,2,...,m. If any 
 point lies outside the interval from X(1) to X(N), a value is 
 extrapolated from the nearest extreme cubic, and a warning is 
 returned.

Parameters

e01bff

Required Input Arguments:

x (:)                                 real
f (:)                                 real
d (:)                                 real
px (:)                                real

Optional Input Arguments:                       <Default>

ifail                                 integer  -1

Output Arguments:
