get

Get operating point information for Stateflow chart, MATLAB System block, or S-function

Since R2019a

Syntax

op = get(modelOP,blockPath)

Description

op = get(modelOP,blockPath) returns the operating point information op for the model element at the specified path blockPath. Use the get function to access operating point information for:

• Stateflow^® charts

• MATLAB System blocks

• S-functions with custom operating point implementation

To access the state for a built-in block, use the loggedStates property of the Simulink.op.ModelOperatingPoint object.

Examples

Get Operating Point for Stateflow Chart

To get the operating point for a Stateflow chart that is inside a referenced model, specify the full path to the chart relative to the top model.

model = 'sldemo_fuelsys_dd';
opt = struct('SaveFinalState','on','SaveOperatingPoint','on','StopTime','1');
simOut = sim(model,opt);
modelOp = simOut.xFinal;
blockPath = 'sldemo_fuelsys_dd/Fuel Rate Controller|sldemo_fuelsys_dd_controller/control_logic';
chartOp = get(modelOp,blockPath)

Input Arguments

modelOP — Model operating point

Simulink.op.ModelOperatingPoint object

Model operating point, specified as a Simulink.op.ModelOperatingPoint object.

blockPath — Path to model element whose operating point you want to access

string | character vector

Path to model element whose operating point you want to access, specified as a string or a character vector.

You cannot access or modify operating point information for Stateflow charts, MATLAB System blocks, or S-functions inside referenced models simulated using accelerator mode.

Output Arguments

op — Element operating point

Stateflow.op.BlockOperatingPoint object | S-function operating point | MATLAB System block operating point

Element operating point, returned as a Stateflow.op.BlockOperatingPoint (Stateflow) object, an S-function operating point, or a MATLAB System block operating point.

Tips

• For more information about working with operating points for Stateflow charts, see Save and Restore Operating Points for Stateflow Charts (Stateflow).

• Use the ssSetOperatingPointVisibility function to specify whether operating point information for an S-function is accessible from the ModelOperatingPoint object.

Version History

Introduced in R2019a

R2019a: Simulink.SimState.ModelSimState is renamed to Simulink.op.ModelOperatingPoint

The Simulink.SimState.ModelSimState object, which was introduced in R2009a, is renamed and replaced with the Simulink.op.ModelOperatingPoint object. You can still use simulation snapshots from a previous release that you captured and saved as ModelSimState objects. When you load the object into the workspace or a model, the object is replaced with a ModelOperatingPoint object that contains the same data.

In most cases, you do not need to update scripts in response to this change. The ModelOperatingPoint object has the same properties as the ModelSimState object. The setBlockSimState and getBlockSimState functions continue to work but are not recommended. Instead, use the get and set functions for the ModelOperatingPoint object.
