Defining a Function

To define a new math function or to modify an existing one, follow these steps:

  1. Use Tools → Mathematics → Functions to open the “Functions” dialog box.
  2. Select the math function you want to edit and click on “Modify”
    • Or “New Function” if you want to create a new function.
  3. The dialog box “Edit Function” appears. It contains three tabs in which you can make all entries pertaining to the math formula.
  4. Once you have finished making your entries or modifications, click on “Save“ or “Save as”.

Notes

  • When a math function is modified, WinDarab immediately function if it is displayed or in use in a window.
  • You can also create a new function by right-clicking into the Channels window and select Math function → New. If you right-click on a function in the Channels window, you can chose to edit this function.
  • Math formulas and channels with identical name are not allowed.
    If a user tries to save a math formula but at least one opened file contains a data channel with the same name, WinDarab asks the user to select a different name for the math formula.
  • WinDarab shows a message, if a file contains data channels with the same name as already defined math formulas. The data channels are not available until the user changes the name of the math formula and reopens the file.
