Problem with code generation using Embedded Coder

I have been trying to use Embedded Coder to generate C code of an optimization algorithm. The algorithm use the lsqlin solver to solve the optimization problem. I have tested the Embedded Coder with simpler algorithms, and it yielded good results. I decided to keep up the testing phase with a slightly more complicated algorithm. However, Embedded Coder breaks down with this new algorithm. For example, the inputs that I define in my MATLAB code aren't used in any part of the C code generated. I defined a cost function variable for the optimization algorithm, and the embedded coder reuse the variable multiple times in different contexts. Some declarations of the MATLAB function does not appear in the C code. For example, I have the following declaration:

 iap = x_1(1);
 ibp = x_1(2);
 icp = -x_1(1)-x_1(2);

And the embedded coder produces the following:

  /* :  iap = x_1(1); */
  /* :  ibp = x_1(2); */
  /* :  icp = -x_1(1)-x_1(2); */
  Gop = (-x_1[0]) - x_1[1];

It once again assign variables to the cost function. Furthermore, variables iap and ibp aren' t being defined and used in the C code. Just icp is assign to Gop. This happens multiple times in the generated code. I thought that maybe the code was just a bit convoluted, but the outputs would be the same compared to the MATLAB counterpart. However, I tested the code in the S-function builder in MATLAB and it doesn't produce any ouputs. I have tried multiple configurations of the Code Generation tool to no avail. Can we get more control over the Embedder Coder?

Kind regards.

I have seen that the embedded coder configuration can be set using coder.EmbeddedCodeConfig. However, I can't find the method to link this configuration to the simulink model from which I want to generate code.

@MathWorks Support Team I'm sorry to tag you, but I do need help with this issue.

Hi @Felipe Herrera,

Will it be possible to share a sample model demonstrating the problem, so that others can reproduce the issue and contribute more effectively ?
