    Syntax

    getScalarizationMethods(sFE,featurename)

    Description

    getScalarizationMethods(sFE,featurename) returns the scalarization methods stored in the ScalarizationMethod property of the time-frequency feature extractor object sFE to extract scalar values from featurename.

    Open Live Script

    Create a signalTimeFrequencyFeatureExtractor object and enable the spectral crest, time-frequency ridges, and instantaneous bandwidth time-frequency-domain features. Specify scalarization methods in the spectral crest and the instantaneous bandwidth features.

    sFE = signalTimeFrequencyFeatureExtractor( ...
    SpectralCrest=true,TFRidges=true,InstantaneousBandwidth=true);
setScalarizationMethods(sFE,"SpectralCrest", ...
    PeakValue=true,StandardDeviation=true)
setScalarizationMethods(sFE,"InstantaneousBandwidth", ...
    ImpulseFactor=true)

    Get the current scalarization methods for each enabled feature.

    getScalarizationMethods(sFE,"SpectralCrest")
    ans = 2×1 string
    "PeakValue"
    "StandardDeviation"


    getScalarizationMethods(sFE,"TFRidges")
    ans = 

  0×0 empty string array

    getScalarizationMethods(sFE,"InstantaneousBandwidth")
    ans = 
"ImpulseFactor"

    To obtain scalar features using the feature extractor object sFE, use the extract function.

    Input Arguments

    Feature extractor object, specified as a signalTimeFrequencyFeatureExtractor object.

    Extracted feature, specified as a string scalar or a character vector.

    Data Types: char | string

    Tips

    • Use the setScalarizationMethods function to specify scalarization methods for the features that you enabled when creating the feature extractor object.
