removeLabelDefinition
Description
removeLabelDefinition(
removes the label definition lss
,lblname
)lblname
from the labeled signal set
lss
. If you want to remove a sublabel, specify
lblname
as a two-element string array or two-element cell array of
character vectors:
The first element is the name of the parent label.
The second element is the name of the sublabel.
Examples
Remove Label Definition
Load a labeled signal set containing recordings of whale songs.
load whales
lss
lss = labeledSignalSet with properties: Source: {2x1 cell} NumMembers: 2 TimeInformation: "sampleRate" SampleRate: 4000 Labels: [2x3 table] Description: "Characterize wave song regions" Use labelDefinitionsHierarchy to see a list of labels and sublabels. Use setLabelValue to add data to the set.
Retrieve a hierarchical list of labels and sublabels.
labelDefinitionsHierarchy(lss)
ans = 'WhaleType Sublabels: [] MoanRegions Sublabels: [] TrillRegions Sublabels: TrillPeaks '
Remove the sublabel that labels peaks in the trill regions.
removeLabelDefinition(lss,{'TrillRegions' 'TrillPeaks'}) labelDefinitionsHierarchy(lss)
ans = 'WhaleType Sublabels: [] MoanRegions Sublabels: [] TrillRegions Sublabels: [] '
Remove the label that specifies the whale type.
removeLabelDefinition(lss,"WhaleType")
getLabelNames(lss)
ans = 2x1 string
"MoanRegions"
"TrillRegions"
Input Arguments
lss
— Labeled signal set
labeledSignalSet
object
Labeled signal set, specified as a labeledSignalSet
object.
Example:
specifies a two-member set of random
signals containing the attribute labeledSignalSet
({randn(100,1)
randn(10,1)},signalLabelDefinition('female'))'female'
.
lblname
— Label or sublabel name
character vector | string scalar | cell array of character vectors | string array
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.
