Simulink.SimulationData.DatasetRef.getDatasetVariableNames

List names of Dataset variables in MAT-file

Syntax

varNames = Simulink.SimulationData.DatasetRef.getDatasetVariableNames(matFile)

Description

varNames = Simulink.SimulationData.DatasetRef.getDatasetVariableNames(matFile) lists the names of variables for Dataset data in a MAT-file.

Examples

List Variable Names in MAT-File

Suppose that you simulate a model using the default variable names for signal logging data and states data. You enable the Configuration Parameters > Data Import/Export > Log Dataset data to file and use the default MAT-file name of out.mat.

List the variable names in the MAT-file.

varNames = Simulink.SimulationData.DatasetRef.getDatasetVariableNames('out.mat')

varNames =
 
   'xout'  'logsout'   

Tips

To get the names of Dataset variables in the MAT-file, using the Simulink.SimulationData.DatasetRef.getDatasetVariableNames function processes faster than using the who, or whos functions.

Input Arguments

matFile — MAT-file that contains Dataset variables

character vector

MAT-file that contains Dataset variables, specified as a character vector. The character vector specifies the path to the MAT-file.

Output Arguments

varNames — Names of Dataset variables in MAT-file

cell array

Names of Dataset variables in MAT-file, returned as a cell array.
