WHAT MIME64 IS: MIME64 is an encoding described in RFC1341 as MIME base64.Its purpose is to encode binary files into ASCII so that they may be passedthrough e-mail gates. In this regard, MIME64 is similar to UUENCODE.Although most binaries these days are transmitted using UUENCODE, Ihave seen a few using MIME64, and I have had requests from friends thatI decode MIME64 files that have fallen into their hands. As long assome MIME64 continues to exist, a package such as this one is usefulto have.

These codes require an ASCII input file interp.dat of the following form: N: Number of Polynomial Interpolation Points (Small) First Sample (x1,y1) Second Sample (x2,y2) ... Nth Sample (xN,yN) N1: Number of Error Evaluation Points (Large) First Sample (x1,y1) Second Sample (x2,y2) ... N1th Sample (xN1,yN1) -These codes will produce two ASCII output files: lagrange.out or newton.out. The first section contains the coefficients of the interpolation polynomial. The second section contains the interpolation polynomial evaluated at the interpolation points, including the error at each interpolation point. The third section contains the overall error of the interpolation polynomial as computed from the error evaluation points. lagrange.plt or newton.plt. The interpolation polynomial evaluated at the error evaluation points.
