- Dear Hugh,
-
- The routine "fit" in the Maple share library is hopefully what you need.
- fit( X, Y, [1,t,t^2], t ); will return a quadratic polynomial in t which
- fits the data X,Y in the least squares sense.
- You can get the routine from the Maple share library using anonyous
- ftp at daisy.uwaterloo.ca or ftp.inria.fr or neptune.inf.ethz.ch
- It's the file maple/5.0/share/fit. Alternatively, using e-mail, send an
- message to maple-netlib@can.nl consisting of the text "send info".
