Simulink.io.MatFile - Read data in MAT file format - MATLAB (original) (raw)
Main Content
Namespace: Simulink.io
Read data in MAT file format
Since R2021a
Description
Simulink.io.MatFile inherits from the Simulink.io.FileType base class. The class reads data formatted in a format used by MAT files. To import data from a MAT file, use this class.
classdef MatFile < Simulink.io.FileType
The Simulink.io.MatFile class is a handle class.
Class Attributes
| Abstract | false |

Properties
MAT file reader, specified as a character array.
Attributes:
| GetAccess | public |

| SetAccess | public |
Data Types: char | string
Methods
These methods specialize standard MATLAB® operators and functions for objects in this class.
| isFileSupported | This method always returns true because it operates only on data in the MAT file. |
|---|---|
| getFileTypeDescription | This method returns the MAT file reader description for MAT files containing data with loading and logging signal formats that Simulink® supports. |
Examples
Read data in MAT file format from the filefoo.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 the dataset to a MAT file namedbar.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);
