MATLAB: How to output all the Simulink model signals’ Output data type

MATLABsimulink

Hi guys, My current project is to findout all the signals' output data type(int16, int32, single, double..). How can I do this? And can i output these information into .CSV file? Thank a lot~

You can use the CompiledPortDataType property of block ports to get the port datatype.

outportBlks = find_system('modelname', 'BlockType', 'Outport');
outportDTs = cell(numel(outportBlks), 1);
modelname([],[],[],'compile')
for i = 1:numel(outportBlks)
  outportBlk = outportBlks{i};
  q=get_param(outportBlk,'PortHandles'); 
  outportDTs{i} = get_param(q.Inport,'CompiledPortDataType');
end
modelname([],[],[],'term');
xlswrite('csvlist.dat',outportDTs);

I used xlswrite because it is the easiest way I could think of to write cell arrays out to a file (although it doesn't separate the strings will commas). You can of course choose one of the several techniques in MATLAB to write the variable outportDTs to a file.

MATLAB: Is there a way to get all the blocks with specific datatype (eg. boolean / ufix1) in Simulink model after compiling

You can't exactly do this for blocks, because some blocks use different data types for different calculations inside of them. What you can do is get the compiled data types of ports, though.

The following code will show you how to do it for all the output ports in the "vdp" shipping example. It should all return double, but try it on one of your models and see what you get!

% Compile the vdp model
vdp([],[],[],'compile');
% Find all blocks in model
allBlocks = find_system('vdp','Type','Block');
% Loop through all blocks
for i = 1:numel(allBlocks)
      lh = get_param(allBlocks{i},'PortHandles');
      outports = lh.Outport;
      % Loop through all output ports
      for j = 1:numel(outports)
          dataType = get(outports(j),'CompiledPortDataType');
          % Display the data type
          disp([allBlocks{i} ' output port ' num2str(j) ': ' dataType]);
      end
    end
% Terminate
vdp([],[],[],'term')

Right... so to get all the blocks with a specific data type, you can use logic like

if strcmp(dataType,'single')
  % do something
end

MATLAB: How to access the port width, data types, and dimensions individually for the blocks in the Simulink model from the MATLAB command line

You can access the port width, data type, and dimensions of individual blocks in a Simulink model by using the GET_PARAM function and the following properties:

"CompiledPortDataType"

"CompiledPortWidth"

"CompiledPortDimensions"

The simulation has to be running or compiled in order for the above properties to return the correct value. You can "compile" the model and then use the GET_PARAM command as follows:-

modelname([],[],[],'compile')
q=get_param(gcb,'PortHandles');
get_param(q.Inport,'CompiledPortDataType')
get_param(q.Inport,'CompiledPortWidth')
modelname([],[],[],'term')

where modelname is the name of your Simulink model.
