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 the Install the Marketplace Client and Plug-ins topic in IDL Help for instructions.
You can now change IDL Workbench themes; for example, you can switch to a dark theme. For details, see the Change the Workbench Theme topic in IDL Help.
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 the Dock and Undock Views topic in IDL Help for details.
SOBOLSEQUENCE
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.
