Load variables from MAT file into Simulink.SimulationInput object

Syntax

Description

simIn = loadVariablesFromMATFile([simIn](#mw%5F34878cb6-05e4-4e05-baba-b64c80b983fb),[filename](#mw%5F05a7b300-c2b0-4815-b076-278b43cdba30)) loads variables from the MAT file filename into theVariables property of the Simulink.SimulationInput simIn.

simIn = loadVariablesFromMATFile([simIn](#mw%5F34878cb6-05e4-4e05-baba-b64c80b983fb),[filename](#mw%5F05a7b300-c2b0-4815-b076-278b43cdba30),'[Append](#mw%5F518afdcc-fc96-4261-8db8-975a697d3760)', 'on') loads variables from the MAT file filename into theVariables property of the Simulink.SimulationInput simIn, while adding to the existing variables in theVariables property instead of replacing them.

Load variables from a MAT file into a Simulink.SimulationInput object using the loadVariablesFromMATFile function.

Create a Simulink.SimulationInput object for the model.

mdl = "ex_loadVar_sldemo_househeat"; simIn = Simulink.SimulationInput(mdl);

Use the loadVariablesFromMATFile function to load variables from a MAT file into the Variables property of the Simulink.SimulationInput object.

simIn = loadVariablesFromMATFile(simIn,"sldemo_househeat_data.mat")

simIn = SimulationInput with properties:

           ModelName: "ex_loadVar_sldemo_househeat"
        InitialState: [0×0 Simulink.op.ModelOperatingPoint]
       ExternalInput: []
     ModelParameters: [0×0 Simulink.Simulation.ModelParameter]
     BlockParameters: [0×0 Simulink.Simulation.BlockParameter]
           Variables: [1×25 Simulink.Simulation.Variable]
           PreSimFcn: []
          PostSimFcn: []
          UserString: ''
VariantConfiguration: ''

The simulation uses the variables loaded into the Simulink.SimulationInput object.

Input Arguments
