    Syntax

    cTable = convertedTable(importer,source)
    [cTable,info] = convertedTable(importer,source)

    Description

    cTable = convertedTable(importer,source) returns a converted table based on the source input. The truth log structures are useful for metric evaluation.

    example

    [cTable,info] = convertedTable(importer,source) also returns info, which contains the platform IDs and class IDs mapping tables.

    Tracking truth data importer, specified as a TrackingTruthDataImporter object. You can use the Tracking Data Importer app to create these objects.

    Data source to read, specified as a string scalar representing the path to a data file, or as a MATLAB table or timetable from workspace.

    For details on the exact format requirements for the file or table, see the display of the importer object.

    Example: "./flight_log.csv"

    Output Arguments
