MATLAB: How to generate code for a model so that the input ports can accept signals of any dimension in Simulink 6.6 (R2007a)

dynamicallyportssimulinksized

I would like to generate code for a model, so that the input ports in the root level of the model can accept data of any dimension. This would be very useful for Image Processing where the input image size is not fixed.

Building a model in which the input port dimensions are not explicitly specified is not supported in Simulink.

To work around this issue, you can create a C S-function which has input ports whose dimensions are dynamically sized.

You can use a MATLAB script to copy the port names to the signal lines in Simulink 6.0 (R14).

There is an example attached to this solution. The script is called when you press the blue subsystem.

MATLAB: How to populate the signal names to match the bus object signal names in the Bus Creator block in Simulink 6.6 (R2007a)

The ability to assign signal names automatically from the specified Bus Object is not available in Simulink 6.6 (R2007a).

It is possible to create a script that automatically assigns the names specified in the Bus Object Elements to the signals connected to the bus object. For an example, download the attached files MainBus.mat, BusToBeNamed.mdl and DefineInputs.m. The Simulink model contains a Bus Creator block assiciated with a Bus Object. The following example MATLAB code can be used to assign the appropriate names to the signals connected to the bus.

load MainBus
open_system('BusToBeNamed');
S = Simulink.Bus.objectToCell({'MainBus'});
blk = 'BusToBeNamed/Bus Creator';  
ph = get_param(blk,'PortHandles');
lh = get_param(ph.Inport,'Line');
N = length(S{1}{4});
for i = 1:N
      set(lh{i},'Name',S{1}{4}{i}{1});
end
