Simulink.ModelWorkspace

Describe a model workspace.

Description

Instances of this class describe model workspaces. Simulink creates an instance of this class for each model that you open during a Simulink session. See Working with Model Workspaces for more information.

Property Summary

Name	Access	Description
DataSource	RW	Specifies the source used to initialize this workspace. Valid values are 'MDL-File' 'MAT-File' 'M-Code'
FileName	RW	Specifies the name of the MAT-file used to initialize this workspace. Simulink ignores this property if DataSource is not 'MAT-File'.
MCode	RW	A string specifying M code used to initialize this workspace. Simulink ignores this property if DataSource is not 'M-Code'.

Method Summary

Name	Description
assignin	Assign a value to a variable in the model's workspace.
clear	Clear the model's workspace.
evalin	Evaluate an expression in the model's workspace.
reload	Reload the model workspace from the workspace's data source..
save	Save the model's workspace to a specified MAT-file.
saveToSource	Save the workspace to the MAT-file that the workspace designates as its data source.
whos	List the variables in the model workspace..

Methods

Purpose:   Assign a value to a variable in the model's workspace.

Syntax:   assignin('varname', varvalue)

Arguments:   
  

• varname

• Name of the variable to be assigned a value.

• varvalue

• Value to be assigned the variable.

Description:   This method assigns the value specified by varvalue to the variable whose name is varname.

See also:   evalin

Purpose:   Clear the model's workspace.

Syntax:   clear

Description:   This method empties the workspace of its variables.

Purpose:   Evaluate an expression in the model's workspace.

Syntax:   evalin('expression')

Arguments:   
  

• expression

• A MATLAB expression to be evaluated.

Description:   This method evalues expression in the model workspace.

See also:   assignin

Purpose:   Reload the model workspace from the workspace's data source.

Syntax:   reload

Description:   This method reloads the model workspace from the data source specified by its DataSource parameter.

See also:   saveToSource

Purpose:   Save the model's workspace to a specified MAT-file.

Syntax:   save('filename')

Arguments:   
  

• filename

• Name of a MAT-file.

Description:   This method saves the model's workspace to the MAT-file specified by filename.

Note    This method allows you to save the workspace to a file other than the file specified by the workspace's FileName property. If you want to save the model workspace to the file specified by the file's FileName property, it is simpler to use the workspace's saveToSource method.

Example:   

• hws = get_param('mymodel','modelworkspace') 
  hws.DataSource = 'MAT-File'; 
  hws.FileName = 'workspace'; 
  hws.assignin('roll', 30); 
  hws.saveToSource;
  hws.assignin('roll', 40);
  hws.save('workspace_test.mat');
  

See also:   reload, saveToSource

Purpose:   Save the workspace to the MAT-file that it designates as its data source.

Syntax:   saveToSource

Description:   This method saves the model workspace designated by its FileName property.

Example:   

• hws = get_param('mymodel','modelworkspace') 
  hws.DataSource = 'MAT-File'; 
  hws.FileName = 'params'; 
  hws.assignin('roll', 30); 
  hws.saveToSource;
  

See also:   save, reload

Purpose:   List the variables in the model workspace.

Syntax:   whos

Description:   This method lists the variables in the model's workspace. The listing includes the size and class of the variables.

Example:   

• >> hws = get_param('mymodel','modelworkspace');
  >> hws.assignin('k', 2);
  >> hws.whos
  
    Name      Size                    Bytes  Class
  
    k         1x1                         8  double array
