PyMatrix is a package to provide access to the functionality of matrix algebra. This package is currently based on numarray. It includes a statistics module which includes a basic analysis of variance. In the future it is hoped to enhance the generality of the divide operation, to add the transcendental functions as methods of the matrix class and to improve the documentation. The expectation is that Numeric3 will eventually replace numarray and that this will necessitate some changes to PyMatrix Downloads in the form of a Windows Installer (Inno) and a zip file are available at: http://www3.sympatico.ca/cjw/PyMatrix An /Introduction to PyMatrix/ is available: http://www3.sympatico.ca/cjw/PyMatrix/IntroToPyMatrix.pdf Information on the functions and methods of the matrix module is given at: http://www3.sympatico.ca/cjw/PyMatrix/Doc/matrix-summary.html Colin W.
