# Global parameter

setup parameter of toolkit

EpsTk uses global variables of octave or Matlab® to get default values for the functions.

All global parameter are defined in the file ‘einit.m’.

Which global parameter are used by function you can see in the description of the function

### Handling

- change defaults permanently: If you want to change any default values, edit the file ‘einit.m’. This file is called by function eopen everytime.
- change temporarily: you can change then global parameter termporarily if you have called ‘eglobpar’ in you programs before. If you need the default values again after modifications of the global parameter, you should use the command ‘esavpar’ and ‘erespar’. ‘esavpar’ saves all global parameters and ‘erespar’ restores the last backup.
