merge
Merge two or more labeled signal sets
Description
merges N labeled signal set objects, lssnew
= merge(lss1,...,lssN
)lss1,...,lssN
,
and returns a labeled signal set lssnew
containing all the members and
label values of the input sets.
Examples
Load a labeled signal set containing recordings of whale songs. Display the names of the set's members and a summary of its label definitions.
load whales
getMemberNames(lss)
ans = 2×1 string
"Member{1}"
"Member{2}"
labelDefinitionsSummary(lss)

Create a new signal set with the same data source, time information, and labels as lss
. Remove the first member of the new set and change the name of the remaining one. Display the names of the new set's members.
newlss = copy(lss);
removeMembers(newlss,1)
setMemberNames(newlss,"YoungOne")
getMemberNames(newlss)
ans = "YoungOne"
Create a label definition that specifies whether a signal corresponds to a calf or to an adult whale. Add the definition to the new labeled signal set and label the member. Remove the label that specifies the moan regions. Display a summary of the new member's label definitions.
calf = signalLabelDefinition("Calf",LabeldataType="logical", ... DefaultValue=false,Description="Is the specimen a calf, or an adult?"); addLabelDefinitions(newlss,calf) setLabelValue(newlss,1,"Calf",true) removeLabelDefinition(newlss,"MoanRegions") labelDefinitionsSummary(newlss)

Merge the two labeled signal sets. Verify that the merged set contains the members, definitions, and labels of the original sets.

Input Arguments
Input labeled signal sets, specified as labeledSignalSet
objects.
All input sets must have the same time information settings and data source type.
Output Arguments
Merged labeled signal set, returned as a labeledSignalSet
object.
The set lssnew
contains a signal source, label definitions, and
label values that are independent of those in the input labeled signal sets.
Changing any of the input labeled signal sets does not affect the merged labeled signal set.
Changing the merged labeled signal set does not affect any of the input labeled signal sets.

Introduced in R2020a
