Syntax

T = labelDefinitionsSummary(lbldefs)
T = labelDefinitionsSummary(lss)
T = labelDefinitionsSummary(___,lblName)
T = labelDefinitionsSummary(___,lblName,"sublbls")

Description

T = labelDefinitionsSummary(lbldefs) returns a table, T, with the properties of the label definitions contained in lbldefs, a vector of signalLabelDefinition objects.

example

T = labelDefinitionsSummary(lss) returns a table, T, with the properties of the label definitions contained in the labeledSignalSet object lss.

T = labelDefinitionsSummary(___,lblName) returns a table with the properties of the label lblName.

T = labelDefinitionsSummary(___,lblName,"sublbls") returns a table of the properties of the sublabels defined for lblName.

lss = 
  labeledSignalSet with properties:

             Source: {2×1 cell}
         NumMembers: 2
    TimeInformation: "sampleRate"
         SampleRate: 4000

        Description: "Characterize wave song regions"

 Use labelDefinitionsHierarchy to see a list of labels and sublabels.
 Use setLabelValue to add data to the set.

Visualize the label properties of the set.

Input Arguments

collapse all

Signal label definitions, specified as a signalLabelDefinition object or a vector of signalLabelDefinition objects.

Example: signalLabelDefinition("Asleep",'LabelType','roi','LabelDataType','logical') can label a region of a signal in which a patient is asleep.

Labeled signal set, specified as a labeledSignalSet object.

Example: labeledSignalSet({randn(100,1) randn(10,1)},signalLabelDefinition("female")) specifies a two-member set of random signals containing the attribute "female".

Label or sublabel name. To specify a label, use a character vector or a string scalar. To specify a sublabel, use a two-element cell array of character vectors or a two-element string array:

  • The first element is the name of the parent label.

  • The second element is the name of the sublabel.

Example: signalLabelDefinition("Asleep",'LabelType','roi') specifies a label of name "Asleep" for a region of a signal in which a patient is asleep during a clinical trial.

Example: {'Asleep' 'REM'} or ["Asleep" "REM"] specifies a region of a signal in which a patient undergoes REM sleep.

Output Arguments
