Introduction

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 implementation details.

Requirements

• An Intel Pentium II compatible computer or newer.
• MATLAB 6.0 or newer.

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.
