getSignals

myFileObj = mldatxfile("MyFile.mldatx");

You can also create a separate interface for each signal in an MLDATX file. To create an array of mldatx.io.Signal objects that each reference a signal in the MLDATX file, use the mldatx.io.File object as input to the getSignals function.

allSigs = getSignals(myFileObj);
allSigs.Name

ans =

    'sineSig'

ans =

    'rampSig'


ans =

    'constSig'

Create an mldatx.io.File object referencing a saved MLDATX file.

myFileObj = mldatxfile("MyFile.mldatx");

Create an interface to the signals in the MLDATX file with names that contain mysig. By default, results are case-insensitive and need not be the whole word.

mySigs = getSignals(myFileObj,Name="mysig");
mySigs.Name

ans =

    'mysig'


ans =

    'mysignal'


ans =

    'mySig1'


ans =

    'mySignal'

To filter signals with whole-word or case-sensitive matching, use the WholeWord or MatchCase name-value arguments. For example, filter the results to include only the signals with matching capitalization.

mySigsCaseMatch = getSignals(myFileObj,Name="mysig",MatchCase=true);
mySigsCaseMatch.Name

ans =

    'mysig'


ans =

    'mysignal'

Create an mldatx.io.File object referencing a saved MLDATX file.

myFileObj = mldatxfile("MyFile.mldatx");

An MLDATX file can contain data from multiple simulation runs. Use the RunIndex filter option to create an interface to only the signals from a particular run. For example, return all the signals in the third run.

mySigsThirdRun = getSignals(myFileObj,RunIndex=3)

Create an mldatx.io.File object referencing a saved MLDATX file.

myFileObj = mldatxfile("MyFile.mldatx");

Simulink.sdi.Signal objects have metadata that specifies the technique used to log the signal such as signal logging, Outport blocks, or the Record block. You can filter signals in the MLDATX file based on the logging origin. For example, return the signals in the MLDATX file that were logged using the Record block.

mySigs = getSignals(myFileObj,Domain="Record")

Create an mldatx.io.File object referencing a saved MLDATX file.

myFileObj = mldatxfile("MyFile.mldatx");

You can get an interface to subset of signals connected to a specific block using the block path. For example, get an interface to the signals connected to the output port of the Playback block in the model myModel.

mySigsPlayback = getSignals(myFileObj,BlockPath="myModel/Playback");

You can combine the BlockPath filter option with the SubPath and PortIndex filters. For example, get an interface to the signal connected to the second port of the Playback block.

mySigPlayback2 = getSignals(myFileObj,BlockPath="myModel/Playback",PortIndex=2);
