  • 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.
