Simulink Model Scaling

Build multi-agent Simulink models from single agent templates.

Reference

flag = SCALE_SIMULINK_MODEL(model_file_name,block_name,N)

A new file containing the contents of the template model_file. will be created. Block block_name will be replicated N times. Its connections will be handled as follows:

• Any input connected to a demultiplexer will have the demultiplexer scaled up to have N outputs. The corresponding input of each newly replicated block will be connected to the respective output of the demultiplexer.

• Any other inputs will be connected together back to the original source port.

• Any output connected to a multiplexer will cause that mutliplexer to be scaled up to have N inputs. The corresponding output of each newly replicated block will be connected to the respective input of the multiplexer.

• Any other output will be left unconnected.

Example

The code below is reproduced from the SCALE_EXAMPLE script provided.

scale_simulink_model('single_example.slx','dynamics',N)

% set the value of the "frequency" block to suit the new problem size
set_param([gcs '/Constant'],'Value',mat2str(1:N))

It takes the single_sxample.slx file pictured below as its template.

Its immediate output is the model shown below.

This is pretty ugly, but tidies up OK with the auto-arrange tool, found in the Simulink Format menu.
