how to generate MATLAB code from Simulink model

Hi, I have a relatively complex simulink model, from which a MATLAB code must be generated. I want to use the generated code in App designer to develop an app and finally compile the app using `Application Compiler`, so that it can be used on every system without having MATLAB installed. The process can be summed up as the following: Simulink --> MATLAB code (.m) --> App Designer --> Application compiler (.exe)

How about direct use sim() to run your model in your App Designer script?

You can do what Kevin suggested and then generate the executable file. Are you facing any issues in doing so?

[Keymand Kiani]

Unfortunately it doesn't work that way; because it must be a stand-alone executable data at the end. as far as MATLAB is instaled and opened it is no problem. The solution that I've found so far is to convert the simulink model to c/c++ code and using mex function to recall it in the MATLAB script. But it doesn't seem to be easy and you have to modify the c++ code that is generated from simulink model! well you must have deep knowledge in c/c++ and MATLAB to handle it.

you generate MATLAB Code from Simulink?

There is no support for what you are doing.

You can use Simulink Real Time Explorer, using instrument panels for user interaction.

As of R2020a you can use Simulink Compiler to compile your model and use it with your deployed / compiled App Designer app.

image = imread('jump.jpg');     % read image

Error using imread>get_full_filename
File "jump.jpg" does not exist.

Error in imread (line 372)
fullname = get_full_filename(filename);

% get image dimensions: an RGB image has three planes
% reshaping puts the RGB layers next to each other generating
% a two dimensional grayscale image
[height, width, planes] = size(image);
rgb = reshape(image, height, width * planes); 
imagesc(rgb);                   % visualize RGB planes
colorbar on                     % display colorbar
r = image(:, :, 1);             % red channel
g = image(:, :, 2);             % green channel
b = image(:, :, 3);             % blue channel 

The result is:

How does this answer the Question about compiling Simulink ?
