Access the Simulink.Bus elements from cell array of Bus objects.

I have cell array containing cell arrays of bus objects with its simulink.bus elements. I want to search the simulink bus element in thos cell with the name of sub bus.

For ex: if I have "Bus" cell array>>with "Sub_Bus" cell arrays>> and Signal 1.simulink bus element in it.

I want to search "signal 1" in Cell "Bus" and also want "sub_bus" name into which signal 1 is placed using matlab code .

Hi @Anju Mohokar,

As per my understanding you have a cell array of cell arrays which contains Simulink.bus elements and you want to search for a signal and wants the “sub_bus” name into which the signal is placed.

I am assuming that the main cell array contains arrays of “sub_bus” which is also a cell array of Simulink.bus elements and the “sub_bus” name is indexed according to the index of the “sub_bus” array in the main cell array.

You can find the “sub_bus” name and signal index with the help of the following MATLAB function which takes main cell array and signal name to search and returns the sub-bus name and signal index as output, I’m assuming the main cell array is an array of cell arrays which contains Simulink.bus elements.

function [subBusName, signalIndex] = findSignalInBus(busCellArray, signalName) 
  % Initialize outputs 
  subBusName = ''; 
  signalIndex = -1; 
  % Iterate over each cell in the main bus cell array 
  for i = 1:length(busCellArray) 
       subBusCellArray = busCellArray{i}; 
       % Iterate over each sub-bus cell array 
       for j = 1:length(subBusCellArray) 
            % Check if the name of the bus element matches the signal name
             if strcmp(subBusCellArray{j}.Name, signalName)
                 subBusName = sprintf('Sub_Bus_%d', i); % Assuming sub-bus naming convention
                 signalIndex = j; 
                 return;
             end
       end
  end
end
