lss

lss = 
  labeledSignalSet with properties:

             Source: {2x1 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.

Remove the second member of the set.

Input Arguments

`lss` — Labeled signal set
`labeledSignalSet` object

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'.

`midxvect` — Subset member row numbers
vector of positive integers

Subset member row numbers, specified as a vector of positive integers. Each element of midxvect specifies a member row number as it appears in the Labels table of the labeledSignalSet object lss.

Example: [2 3 5 7 11 13 17] chooses a subset of signals indexed by prime numbers.
