how can we create simulink block using m file in matlab 2012a?

 i have created my m file in matlab is there any way to create a simulation block without using s function

Answer 1

[Azzi Abdelmalek]

you can use

1. new_system('ModelName') to create a simulink model
2. open_system('ModelName') to open your model
3. add_block('Simulink/Sources/step','ModelName/BlockName') % for example
4. set_param to configure blocks
5. use add_line to connect block
6. sim('ModelName',options) to start simulation
7. close_system, to close your simulink Model

Azzi: I think Kanwal's question is about calling his MATLAB code from Simulink, not about constructing a model using MATLAB code.

[Salim]

I think he misunderstood your question. You can use Matlab function block under User-defined functions.

You can use the Interpreted MATLAB Function block if your function has one input and one output, and you don't intend to generate code from your model. Otherwise, you can try the (Embedded) MATLAB Function block. If you're not using the subset of functions supported for code-generation, you will need to declare those using coder.extrinsic.
