POLYMATH Software - [Support] Polymath 5.1 Builds 228-232

Polymath 5.1 Builds 228-232

Installation - These builds are the first that have utilized InstallShield software to create the setup files. This software uses the latest the Windows Installer service. Note that some operating systems will need to be rebooted up to two times during the POLYMATH installation process.

International Users - If you are having difficulties with POLYMATH calculations, this may be due to your regional settings for your Windows operating system. Please go to Start/Settings/Control Panel/Regional Options/General and specify:

Locale: English Language Settings: Western Europe and United States

Under Start/Settings/Control Panel/Regional Options/Numbers - Please make sure that the standard settings are used for Numbers.

Intrinsic Functions - The fact( ) function for factorials is inoperative and the sqr( ) function should not be used as it returns the square root.

Integration Performance - The STIFF and STIFFBS integration algorithms in the Ordinary Differential Equation Solver may not always respond to a Ctrl+ C to abort command. A Ctrl + Alt + Del should allow Polymath to be stopped, but the current problem may be lost if it has not been previously saved.
Nonlinear Regression Performance - The convergence of the solution may at times be incomplete due to the initial estimates. Try to give good initial estimates for best results.

Please report problems to Dr. M. B. Cutlip.
