fenchel: Fenchel conjugates and subdifferentials in Maple

Overview

  • fenchel is a collection of Maple commands written by Heinz Bauschke and Martin von Mohrenschildt. It allows the symbolic computation of Fenchel conjugates and sudifferentials for convex functions defined on the real line.

  • Using fenchel (Version 99.05.07 for Maple VR5):
    1. Click here and save the file as fenchel.m
    2. Start Maple.
    3. In Maple, issue the command read(`fenchel.m`);.
    4. You then can use fenchel. For instance, type conj(convert(exp(x),cf),y);.
