Matsim is a high level interface to create Simulink models from aMatlab script. Matsim is a wrapper around the standardsimulink API that makes building a simulink model programmatically much faster.
- Automatic layout (no need to specify block positions!)
- Intuitive interface (you can "add", "subtract", "multiply", ... simulink blocks)
- Extensible library (easily add new blocks from your custom libraries)
| Source script (.m) | Resulting model | Notes |
|---|---|---|
c = Constant(1) |  | Create a Constant block with value 1 |
res = a+b |  | Create an Add block and connect its inputs to blocksa andb |
res = [a,b] |  | Create an Mux block and connect its inputs to blocksa andb |
res = Max(a,b) |  | Create an MinMax block and connect its inputs to blocksa andb |
res = 1 - u1./(u2.*u3) |  | Create a group of simulink blocks that computes a complex expression |
Scope(Gain(FromWorkspace('var'),'Gain',0.5)) |  | Easily combine blocks |
The automatic layout feature relies onGraphViz, which you need to install separately.
- InstallGraphViz and add it to the system PATH
- Download and extract the Matsim package (fromFile Exhange or from here)
- Add Matsim folder (and subfolders) to the Matlab path
Quick example to get started. For more check thetests folder.
