New Features

IDL Workbench

  • New to IDL is that you can install the Eclipse Marketplace Client in the IDL Workbench. The Eclipse Marketplace Client is an interface that allows you to browse and install Eclipse-based plug-ins. See Install the Marketplace Client and Plug-ins for steps.

  • You can now change IDL Workbench themes, for example, you can switch to a dark theme. For details, see Change the Workbench Theme.

  • A File > Restart option has been added to the IDL Workbench main menu to enable exiting and restarting the Workbench with a single menu option.
  • The Editor view can be undocked as well as moved to a separate monitor. See Dock and Undock Views for details.


The new SOBOLSEQUENCE function generates numbers from the Sobol sequence. A Sobol sequence is a low discrepancy quasi-random sequence. Sobol sequences were designed to fill space in a more uniform manner than completely random sampling. See SOBOLSEQUENCE for details.


IDL Workbench Internationalization

The IDL Workbench previously included several different languages; with this release, you will need to install new languages from the Babel Language Pack repository available in Eclipse. See Install the Marketplace Client and Plug-ins and Set IDL Workbench Internationalization for details.

Added Keyword to EIGENQL

Added the SYMMETRY_RTOL keyword to EIGENQL, to specify a value that represents the maximum acceptable relative tolerance to be allowed when verifying that the array is symmetric.
