Group of factory settings and factory subgroup objects

Since R2019b


A FactoryGroup is an object within the factory settings tree. At the top of the tree is the root FactoryGroup. Each FactoryGroup can contain a collection of other FactoryGroup and FactorySetting objects. For more information about creating a factory settings tree, see Create Factory Settings for Toolboxes.


Create the FactoryGroup root object using the matlab.settings.FactoryGroup.createToolboxGroup function. For example:

myToolboxSettings = matlab.settings.FactoryGroup.createToolboxGroup('mytoolbox','Hidden',false);

Name of factory group, specified as a character vector or string.

Hidden state, specified as true or false.

When set to true, the factory group, including all factory groups and factory settings within the group, do not display in the Command Window or as part of tab completion, although they remain accessible.

Function to validate factory settings in group, specified as a function handle. When specified, the function is used to validate the values of all factory settings within the group, except for settings that specify their own validation functions. This includes settings in subgroups, as long as the subgroup or settings do not specify their own validation functions.
