In order to evaluate f(x) from this set of points, one needs to find J such that x(J) x x(J+1). This is accomplished by the subroutines (locate.for and LOCATE.C) described in Locate.doc. Conversion of this file into a linear function is covered in FileFun.doc. Once these points have been found Lagrange.doc is a good way to interpolate between these points to convert a collection of data points into a function.
