Examples
Display Information On Definitions Stored in Label Definition Creator Object for Multisignal Workflow
Load an existing label definition table.
labelDefFile = fullfile(toolboxdir('driving'), 'drivingdata', 'labelDefsMultiSignal.mat'); ld = load(labelDefFile)
ld = struct with fields:
labelDefs: [6x6 table]
Create a labelDefinitionCreatorMultisignal
object from the label definitions table.
ldc = labelDefinitionCreatorMultisignal(ld.labelDefs)
ldc = labelDefinitionCreatorMultisignal contains the following labels: Car with 0 sublabels and 0 attributes and belongs to None group. (info) LeftLane with 0 sublabels and 0 attributes and belongs to None group. (info) Road with 0 sublabels and 0 attributes and belongs to None group. (info) Sunny with 0 sublabels and 0 attributes and belongs to None group. (info) Urban with 0 sublabels and 0 attributes and belongs to None group. (info) For more details about attributes and sublabels, use the info method.
Add an attribute 'Color'
to the label 'Car'
. Specify the attribute type as 'List'
and add items to the list.
addAttribute(ldc,'Car','Color','List',{'Red','Green','Blue'});
Display the details of the updated labelDefinitionCreatorMultisignal
object.

Description: ' '
Display the field ListItems
in the 'Color'
attribute of the label 'Car'
.
colorStruct.ListItems

{'Red'} {'Green'} {'Blue'}
Input Arguments
ldc
— Label definition creator for multisignal workflow
labelDefinitionCreatorMultisignal
object

object.
name
— Name of label, sublabel, or attribute
character vector | string scalar
Name of label, sublabel, or attribute in the ldc
object,
specified as a character vector or string scalar whose form depends on the type of name
you specify.
