getResultsByName

Return signal comparison results based on signal name

Since R2022b

Syntax

diffSig = getResultsByName(diffRes,sigName)

Description

diffSig = getResultsByName(diffRes,sigName) returns the signal comparison result for the signal named sigName in the run comparison results object diffRes.

The output of the function getResultsByName depends on the signal that is being compared.

• If the result that corresponds to sigName is a real, scalar signal, then diffSig is a Simulink.sdi.DiffSignalResult object.

• If the result that corresponds to sigName is a complex signal, a multidimensional signal, or a bus, then diffSig is an array of Simulink.sdi.DiffSignalResult objects. The size of the array corresponds to characteristics of the comparison result.

Examples

Get Comparison Results By Name

Load the Simulation Data Inspector session file getResultsByNameData. The file contains data logged from two simulations of the model getResultsByNameModel, which logs data for five signals.

Simulink.sdi.load("getResultsByNameData.mldatx");

Access the run IDs for the two runs loaded from the file.

runIDs = Simulink.sdi.getAllRunIDs;
baselineID = runIDs(end-1);
comparedToID = runIDs(end);

Compare the two runs.

diffResult = Simulink.sdi.compareRuns(baselineID,comparedToID);

Use the function getResultsByName to access comparison results for the signal ScalarOut.

compareSig = getResultsByName(diffResult,"ScalarOut")

compareSig = 
  DiffSignalResult with properties:

             Name: 'ScalarOut'
           Status: WithinTolerance
          AlignBy: 'Path'
        SignalID1: 4847
        SignalID2: 4927
    MaxDifference: 0
            Sync1: [1x1 timeseries]
            Sync2: [1x1 timeseries]
             Diff: [1x1 timeseries]

Get Comparison Results for Complex Signal

Load the Simulation Data Inspector session file getResultsByNameData. The file contains data logged from two simulations of the model getResultsByNameModel, which logs data for five signals, including the complex signal ComplexOut.

Simulink.sdi.load("getResultsByNameData.mldatx");

Access the run IDs for the two runs loaded from the file.

runIDs = Simulink.sdi.getAllRunIDs;
baselineID = runIDs(end-1);
comparedToID = runIDs(end);

Compare the two runs.

diffResult = Simulink.sdi.compareRuns(baselineID,comparedToID);

Use the function getResultsByName to access comparison results for the complex signal ComplexOut.

compareComplex = getResultsByName(diffResult,"ComplexOut")

compareComplex=1×2 DiffSignalResult array with properties:
    Name
    Status
    AlignBy
    SignalID1
    SignalID2
    MaxDifference
    Sync1
    Sync2
    Diff
    Options

You can also use the function getResultsByName to access comparison results for the real or imaginary parts of the signal by specifying (real) or (imag) as part of the signal name.

compareComplexReal = getResultsByName(diffResult,"ComplexOut (real)")

compareComplexReal = 
  DiffSignalResult with properties:

             Name: 'ComplexOut (real)'
           Status: WithinTolerance
          AlignBy: 'Path'
        SignalID1: 1647
        SignalID2: 1727
    MaxDifference: 0
            Sync1: [1x1 timeseries]
            Sync2: [1x1 timeseries]
             Diff: [1x1 timeseries]

Get Comparison Results for Nonscalar Signal

Load the Simulation Data Inspector session file getResultsByNameData. The file contains data logged from two simulations of the model getResultsByNameModel, which logs data for five signals, including two multidimensional signals: SmallMux and LargeMux.

Simulink.sdi.load("getResultsByNameData.mldatx");

Access run IDs for the two runs loaded from the file.

runIDs = Simulink.sdi.getAllRunIDs;
baselineID = runIDs(end-1);
comparedToID = runIDs(end);

Compare the two runs.

diffResult = Simulink.sdi.compareRuns(baselineID,comparedToID);

Use the function getResultsByName to access comparison results for LargeMux and SmallMux. By default, when you compare runs that contain signals with multidimensional sample values, the Simulation Data Inspector expands the signal to channels and compares the channels. For more information, see Analyze Multidimensional Signal Data.

compareLargeMux = getResultsByName(diffResult,"LargeMux")

compareLargeMux=1×5 DiffSignalResult array with properties:
    Name
    Status
    AlignBy
    SignalID1
    SignalID2
    MaxDifference
    Sync1
    Sync2
    Diff
    Options

compareSmallMux = getResultsByName(diffResult,"SmallMux")

compareSmallMux=1×2 DiffSignalResult array with properties:
    Name
    Status
    AlignBy
    SignalID1
    SignalID2
    MaxDifference
    Sync1
    Sync2
    Diff
    Options

You can access comparison results for an element within a multidimensional signal using the index of the element within the logged signal. For example, get comparison results for the fourth element of the LargeMux signal.

compareElement = compareLargeMux(4)

compareElement = 
  DiffSignalResult with properties:

             Name: 'LargeMux(4)'
           Status: WithinTolerance
          AlignBy: 'Path'
        SignalID1: 4407
        SignalID2: 4411
    MaxDifference: 0
            Sync1: [1x1 timeseries]
            Sync2: [1x1 timeseries]
             Diff: [1x1 timeseries]

Get Comparison Results for Bus

Load the Simulation Data Inspector session file getResultsByNameData. The file contains data logged from two simulations of the model getResultsByNameModel, which logs data for five signals, including a bus.

Simulink.sdi.load("getResultsByNameData.mldatx");

Access the run IDs for the two runs loaded from the file.

runIDs = Simulink.sdi.getAllRunIDs;
baselineID = runIDs(end-1);
comparedToID = runIDs(end);

Compare the two runs.

diffResult = Simulink.sdi.compareRuns(baselineID,comparedToID);

Use the function getResultsByName to access the comparison results for BusOut.

compareBus = getResultsByName(diffResult,"BusOut")

compareBus=1×4 DiffSignalResult array with properties:
    Name
    Status
    AlignBy
    SignalID1
    SignalID2
    MaxDifference
    Sync1
    Sync2
    Diff
    Options

You can also get comparison results for bus elements. Use the function getResultsByName to access the comparison results for the signal Constant 4 inside the bus BusOut.

compareConst4 = getResultsByName(diffResult,"BusOut.Constant_4")

compareConst4 = 
  DiffSignalResult with properties:

             Name: 'BusOut.Constant_4'
           Status: WithinTolerance
          AlignBy: 'Path'
        SignalID1: 37
        SignalID2: 117
    MaxDifference: 0
            Sync1: [1x1 timeseries]
            Sync2: [1x1 timeseries]
             Diff: [1x1 timeseries]

Input Arguments

diffRes — Run comparison results

Simulink.sdi.DiffRunResult object

Run comparison results that contain the signal result you want to access, specified as a Simulink.sdi.DiffRunResult object.

sigName — Name of signal result in run comparison results

string | character vector

Name of the signal in the run comparison results, specified as a character vector or string.

To access a bus element, specify the path to the element through the hierarchy of the bus. For example, to access comparison results for the signal Sine inside the bus BusOut, specify sigName as "BusOut.Sine".

sineRes = getResultsByName(diffRes,"BusOut.Sine");

To access only the real or imaginary result for a complex signal, append the signal name with either (real) or (imag). For example, to access the comparison results for the imaginary part of the complex signal ComplexOut, specify sigName as "ComplexOut (imag)".

imagRes = getResultsByName(diffRes,"ComplexOut (imag)");

Data Types: char | string

Output Arguments

diffSig — Comparison results for specified name

Simulink.sdi.DiffSignalResult object | array of Simulink.sdi.DiffSignalResult objects

Comparison results for specified name, returned as a Simulink.sdi.DiffSignalResult object or an array of Simulink.sdi.DiffSignalResult objects.

The type of output returned by getResultsByName depends on the sigName input.

sigName Input	diffSig Result
Uniquely named scalar signal	Simulink.sdi.DiffSignalResult object
One of N scalar signals with the same name	1×N array of Simulink.sdi.DiffSignalResult objects
Complex signal	1×2 array of Simulink.sdi.DiffSignalResult objects that contain the real and imaginary results
Vector or matrix signal with N elements	1×N array of Simulink.sdi.DiffSignalResult objects
Bus	1×N array of Simulink.sdi.DiffSignalResult objects, where N is the number of elements in the bus

Note

If you specify a name for sigName that is not in the run comparison results, then the function returns an empty array.
