Simulink model to .NET dll using MATLAB Compiler SDK & Simulink Compiler. new_system

Please help me , How to use the below functions for deploying Simulink model to .NET dll using MATLAB Compiler SDK & Simulink Compiler.

new_system

load_system

open_system

save system

add_block

add_line

close_system

Thanks in advance,

Hi Rajesh,

Assuming you are creating the Simulink model programmatically, here is the sample code that creates a Simulink model with a constant and gain block:

% Step 1: Create a new Simulink model
new_system('myModel');
open_system('myModel');

% Step 2: Add blocks to the model
add_block('built-in/Constant', 'myModel/ConstantBlock');
add_block('built-in/Gain', 'myModel/GainBlock', 'Gain', '5');
add_block('built-in/Scope', 'myModel/ScopeBlock');

% Step 3: Connect the blocks
add_line('myModel', 'ConstantBlock/1', 'GainBlock/1');
add_line('myModel', 'GainBlock/1', 'ScopeBlock/1');

save_system('myModel');
close_system('myModel', 1);

"compiler.build.dotNETAssembly" does not directly support Simulink (.slx) files hence you need to create a wrapper code for this and save this code in a MATLAB file (lets say simulateModel.m) as below:

function output = simulateModel(input)
    % Load the Simulink model
    load_system('myModel');

    % Simulate the model
    simOut = sim('myModel');

    % Extract output from simulation results
    % Assuming 'yout' is the output signal
    output = simOut.yout;

    % close the system after simulation
    close_system('myModel', 0);
end

Once the MATLAB file is created you can use MATLAB Compiler SDK to compile the function into a .NET assembly:

load_system('myModel');

% Build the model
slbuild('myModel');

% Package the model into a .NET assembly
compiler.build.dotNETAssembly('simulateModel.m', 'AssemblyName', 'MySimulinkModel', 'OutputDir', fullfile(pwd, 'output'));
close_system('myModel', 0);

You can find additional information on creating a .NET assembly for deployment at the following link: https://www.mathworks.com/help/compiler_sdk/dotnet/compiler.build.dotnetassembly.html

Hope this resolves your issue!!
