Read data in MAT-file format from file, foo.mat.

fileName = 'foo.mat';
aReader = Simulink.io.MatFile(fileName);
resultOfWhos = whos(aReader);

Load the reader, which has no inputs.

varsOnFileStruct = load(aReader);

Load one variable.

var = loadAVariable(aReader,'ts');

Import all the variables from the MAT-file, foo.mat.

importedVars = import(aReader);

Export to a MAT-file, bar.mat.

ds = Simulink.SimulationData.Dataset;
ds = ds.addElement(timeseries([1:10]',[1:10]'),'Signal1');
ds = ds.addElement(timeseries([1:10]',[11:20]'),'Signal2');
ds = ds.addElement(timeseries([1:10]',[21:30]'),'Signal3');

filePath = 'bar.mat';
didWrite = aReader.export(filePath,{'ds'},{ds},0);
