New Features


IDL Machine Learning

The new IDL Machine Learning framework provides a powerful and flexible way to run machine learning applications on numerical data. You can create and train models and apply them in classification, clustering, or regression. For example:

For a complete list with links to all of the functions and classes of the framework, see IDL Machine Learning.

For details on how to get started with IDL Machine Learning, see The IDL Machine Learning Framework.

IDL Package Manager

The IDL Package Manager (IPM) allows you to create, install, update, and remove IDL packages. IDL packages are a collection of files and/or folders that are compressed into a ZIP file; they can contain any combination of IDL pro code, IDL save files, and/or IDL DLMs, and they contain an idlpackage.json file that describes the package. Packages are installed to the directory defined by the new IDL_PACKAGE_PATH preference, and the IDL path is automatically updated to include the new files.

The following libraries are available to be consumed:

Library

IPM Command to Install

IDL-Motley

ipm, /install, 'https://github.com/hadfieldnz/idl-motley'

IDL-ROMS

ipm, /install, 'https://github.com/hadfieldnz/idl-roms'

IDL-Salvaggio

ipm, /install, 'https://github.com/csalvaggio/IDL_RIT_Salvaggio'

IDLdoc

ipm, /install, 'http://packages.idldev.com/idldoc.zip'

Mankoff

ipm, /install, 'https://github.com/mankoff/kdm-idl'

mglib

ipm, /install, 'http://packages.idldev.com/mglib.zip'

mgunit

ipm, /install, 'http://packages.idldev.com/mgunit.zip'

CW_COLORGRADIENT Function

The CW_COLORGRADIENT function creates a compound widget to create color palettes built as gradients interpolated between a series of user-defined colors.

DIALOG_COLORGRADIENT Function

The DIALOG_COLORGRADIENT function allows you to interactively define a color table as a gradient interpolated between a series of user-defined colors.

Updates


ARRAY_EQUAL DIFFERENT_LENGTHS Function and NAN Keyword

The ARRAY_EQUAL function has a new DIFFERENT_LENGTHS keyword, which allows comparing arrays of different sizes on the common indices. It also has a new NAN keyword, which treats NaN values as being equal.

IDLTask Schema Property

A TAGS property was added to IDLTask to help categorize tasks. Because of this update to the task template, the task schema key is now idltask_1.2.

JSON_PARSE Performance

The JSON_PARSE function performance has been improved. Performance improvements will be most noticeable when parsing larger files, where the process will be up to 10 times faster.
