1. Overview
This package provides improved implementations of the error function for
MATLAB. It ships a MEX-file for calculating the error function of real-
valued numbers 5-6x faster than with the default MATLAB implementation.
A second MEX-file and/or a companion M-file enhances the calculation of
the error function for complex numbers. See "erfz.pdf" for implementa-
tion details.
2. Requirements
An Intel Pentium II compatible computer or newer.
MATLAB 6.0 or newer running.
3. Installation
Unpack the archive in a folder that is part of the MATLAB path. The error
functions should reside in a '@double' folder to avoid potential data type
conflicts.
4. Copyright
This software is published as freeware. The author reserves the right to
modify any of the contained files.
You are allowed to distribute the functions as long as you deliver for free the
entire package.

5. Warranty
Any warranty is strictly refused and you cannot anticipate any financial or
technical support in case of malfunction or damage.
Feedback and comments are welcome. I will try to track reported problems and
fix bugs.
