How can I use the MATLAB command to change the simulation of the simulink model?

Common commands:
Simulation command:
Sim --- run a simulation of the simulation of a chain
Sldebug --- debug a Simulink Module
Simset --- set simulation parameters
Simget --- obtain simulation parameters

Line and organize commands:
Linmod-obtain a linear model from a continuous time System
Linmod2 --- also used to obtain linear models, using advanced methods
Dinmod-obtain a linear model from a Discrete Time System
Trim --- find stable state parameters for a simulation system

Build model command:
Open_system -- open an existing model
Close_system -- disable the opened model or module
New_system -- create a new empty model window
Load_system -- load existing models and make them invisible
Save_system -- save an open model
Add_block -- Add a new module
Add_line -- add a line (line between two modules)
Delete_block -- delete a module
Delete_line -- delete a line
Find_system -- find a module
Hilite_system -- make a module conspicuous
Replace_block -- replace an existing module with a new module
Set_param -- set parameters for the model or module
Get_param -- get the parameters of a module or model
Add_param -- add custom string parameters to a model
Delete_param -- delete a user-defined parameter from a model
Bdclose -- close a Simulink window
Bdroot -- Module name at the root level
GCB -- get the name of the current Module
Gcbh -- get the handle of the current Module
GCS -- get the name of the current system
Getfullname -- get the full path name of a module
Slupdate -- upgrade 1. x modules to 3. x modules.
Addterms -- add the terminators module for unconnected ports
Boolean -- convert a numeric array to a Boolean Value
Slhelp -- help of User Wizard or module in the simulation environment

Encapsulation command:
Hasmask -- check whether existing modules are encapsulated
Hasmaskdlg -- check whether an existing module has an encapsulated dialog box
Hasmaskicon -- check whether existing modules have encapsulated icons
Iconedit -- use the ginput function to design module icons
Maskpopups -- Return and change the pop-up menu items of the encapsulation Module
Movemask -- re-build the built-in encapsulation module as the encapsulated sub-module

Diagnostic command:
Sllastdiagnostic-last diagnosis information
Sllasterror -- last error message
Sllastwarning -- last warning message
Sldiagnostics -- obtains the number and compilation status of modules for a model.

Command for hard copy and printing:
Frameedit -- edit the Print Screen
Print -- print the image as an image or save the image as an M file.
Printopt -- default printer settings
Orient -- set the direction of the paper
