HFT.m

Sheldon Axler

The HFT.m Mathematica software package performs symbolic manipulation of expressions that arise in the study of harmonic functions. This software, which is available electronically without charge, can perform symbolic calculations that would take a prohibitive amount of time if done without a computer. For example, the Poisson integral of any polynomial can be computed exactly.

Some of the capabilities of this software:

The HFT.m Mathematica software package will work on any computer that runs Mathematica. Click below to obtain the appropriate version of the HFT.m software package.

Click below to obtain the appropriate documentation. Starting with Mathematica version 5, the documentation for each HFT.m software package is a Mathematica notebook. For earlier versions of Mathematica, the documentation was a pdf file.

The HFT.m software package is generated by a Mathematica notebook called HFT.nb (except in Mathematica version 2, where the notebook suffix was ma instead of nb). The HFT.nb notebook is not needed to use the HFT.m software package. The HFT.nb notebook is easier for a human to read than the HFT.m software package. Thus the HFT.nb notebook is needed only to examine or change the programming of the HFT.m software package. The HFT.nb notebook and HFT.m software package are linked, so changes made in the HFT.nb notebook will generate a changed HFT.m software package without notifying the user. If you intend to make changes in the HFT.nb notebook, change the name of the notebook first (then changes to the notebook will result in a software package with a new name). Click below to obtain the appropriate HFT.nb notebook.
