Simulink.io.SLDVMatFile Class

Namespace: Simulink.io

Read Simulink Design Verifier format data in MAT file

Since R2022a

Description

The Simulink.io.SLDVMatFile class inherits from the Simulink.io.MatFile reader class, which inherits from the Simulink.io.FileType base class. This class reads the data in the sldvData structure used by Simulink^® Design Verifier™. The data is contained in a MAT file. To import data from a MAT file that contains the sldvData structure, use this class.

classdef Simulink.io.SLDVMatFile < Simulink.io.MatFile

The Simulink.io.SLDVMatFile class is a handle class.

Specialized Operators and Functions

These methods specialize standard MATLAB^® operators and functions for objects in this class.

export	Not available.
import	[importedData, warnStr ] = import(reader) To import custom signals for a custom file type, identify the custom file type reader as a Simulink.io.FileType object. The method returns the found variable as a cell array of signal variables of supported types. For more information on supported types, see Choose a Base Workspace and MAT-File Format. The method returns a structure with two fields, Data and Name. Data is a cell array of signals. Name is a cell array of character vectors of the corresponding signal names.
importAVariable	varOut = importAVariable(reader,variableName) To import a specified variable for a custom file type, identify the custom file type reader as a Simulink.io.FileType object. Use VariableName, specified as a character array, to extract the desired signal from the file of custom format signals. The method returns the found variable, returned as a cell array of signal variables of supported types. For more information on supported types, see Choose a Base Workspace and MAT-File Format.
load	This method calls the loadImpl method. Load the signal listed in the custom file type.
loadAVariable	This method calls the loadAVariableImpl method. Validate the format of the signals in the custom MAT file fileName with the associated Simulink.io.FileType reader.
validateFileName	This method calls the validateFileNameImpl method. Validate the format of the signals in the custom MAT file fileName with the associated Simulink.io.FileType reader.
whos	This method calls the whosImpl method. Return the list of sldvData structure datasets.

Examples

Read Data in Simulink Design Verifier MAT File Format

List the test cases in a Simulink Design Verifier MAT file. The whos() method returns a structure with the fields name and type. The structure contains the names of all the test cases in the sldvData structure file along with the type Dataset.

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

Load the data. The load() method converts the test case data in the sldvData structure into Simulink.SimulationData.Dataset objects. The result is a structure where each field is the name of the test case and the value is the corresponding dataset object.

loadedVars = load(aReader);

Import the data. Similarly to load(), the import() method converts the test case data in the sldvData structure into Simulink.SimulationData.Dataset objects. The result is a structure with fields Data and Names. The Names field contains the name of the test cases. The Data field contains the corresponding dataset objects.

importedVars = import(aReader);
