expand all

Custom attribute name, specified as a character array.

Name-Value Arguments

expand all

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: 'Description','My new description.'

Custom attribute description, specified as the comma-separated pair consisting of 'Description' and a character array.

Example: 'Description','My new description.'

Combobox list options, specified as the comma-separated pair consisting of 'List' and a cell array. The list of options is valid only if 'Unset' is the first entry. 'Unset' indicates that the user hasn't chosen an option from the combo box. If the list does not start with 'Unset', it will be automatically appended as the first entry.

Example: 'List',{'Unset','A','B','C'}

Note

You can only use this name-value pair when the Type property of the custom attribute that you're updating is Combobox.
