How I can run a simulink model from Python script?

Hi, I'm trying to write a script in Python that generate number of inputs, and use them as inputs in a Simulink model. My doubt is how to run a Simulink model from Python (I'm working in windows). Could someone help me?

Thanks

You may consider MATLAB Engine API for Python:

http://www.mathworks.com/help/matlab/matlab-engine-for-python.html

For example:

 >>>import matlab.engine
 >>>eng = matlab.engine.start_matlab()
 >>>eng.sim("vdp")

Thanks! Do you also know how I can take a variable from the Workspace of Matlab (after the simulation finish to run) as pass it to Python?

[Bo Li]

Use workspace like following:

 >>>import matlab.engine
 >>>eng = matlab.engine.start_matlab()
 >>>x = 4.0
 >>>eng.workspace['y'] = x
 >>>python_y = eng.workspace['y']

Would you please illustrate how can I use "set_param" command in python to call Simulink file?

[Wade]

I did it in this way:

>> import matlab.engine

>> Matlab = matlab.engine.start_matlab('-desktop')

>> h = Matlab.new_system('NewModelName')

>> s = Matlab.add_block('simulink/Sources/From Workspace',NewModelName+'/DataIn')

>>Matlab.set_param(NewModelName+'/DataIn','Position',matlab.double([150,150,250,250]),nargout=0)

@Bo Li,

I tried in python like you commented before .it is working completely fine but

i want to run the simulink model in C code and Engine Api

I could find any reference for that.Could you please help me?
