How to I use get param to get a value from an output of a bus?
how do i use getparam() to get the value of an specific bus signal? for example getparam(bus selector,signal1, value ) but the function getparam only accepts 2 arguments how do i do it?

In MATLAB, you can use the get_param function to retrieve parameter values from a Simulink block. If you want to get a value from the output of a Simulink bus signal, you would first need to access the block connected to that output and then use get_param to retrieve the parameter value you're interested in.
Here's an example of how to use get_param to get a value from the output of a Simulink block:
% Specify the name of the Simulink model model_name = 'YourSimulinkModel'; % Specify the name of the block whose output you want to access block_name = 'YourBlockName'; % Specify the name of the parameter you want to retrieve param_name = 'YourParameterName'; % Get a handle to the block block_handle = get_param([model_name '/' block_name], 'Handle'); % Use get_param to retrieve the parameter value param_value = get_param(block_handle, param_name); % Display the parameter value disp(['The value of ' param_name ' is: ' param_value]);In this code:
model_name should be replaced with the name of your Simulink model.block_name should be replaced with the name of the block whose output you want to access.param_name should be replaced with the name of the parameter you want to retrieve.The code first gets a handle to the block using get_param with the block's full path (including the model name). Then, it uses get_param again to retrieve the parameter value and displays it.
Make sure to replace the placeholders in the code with the actual names of your Simulink model, block, and parameter.
