Customize name of code generated called M-FIles

I have a simulink model containing Matlab Function blocks, these ones:

Inside the blocks I have code like this that calls other M-Functions saved in the same folder (this is just a simple example to ilustrate the problem).

My purpose is to generate code from the simulink model, I selected the ert.tlc system target file.

Because I want the called M-Functions (in this example would be the function sec_cuc) to be generated in different C-Files (no code inlining), I enabled the option 'Shared location', as seen in the picture below, which enables all the M-Functions to be saved in the same directory when the code is generated:

After generating the code, the generated files have the name :

knopohdjbiecbaaa_sec_cuc.c knopohdjbiecbaaa_sec_cuc.h (the first part of the names change with the different builds, making the generated code unreliable, they all have names like this with the first part to appear completely random and different from each other)

How can I customize the name or just take out the first part of the name with the random letters? My naming options configuration are:

I appreciate any help! Cheers

Right click the block, select "Block Parameters (Subsystem)", select the "Code Generation" panel, For "Function packaging", select "Reusable function", then you can set the "Function name options" and "File name options".

I am not referring to the function in the block (the EarthRot in the example, that one I can set the name), but to the called function, the sec_cuc() in the example.

[Fangjun Jiang]

Good point. Sorry for missing that.

In that case, I've tried creating a Simulink function at the save level where you have your MATLAB function block.

Inside the Simulink function, use another MATLAB function block.

Inside the MATLAB function block, copy and past the M-script for sec_cuc.m

Then generate the code.

Thank you very much for your response, the name can be changed, however with that solution the generated code is very much terrible. (The purpose of my work is to investigate the code generation).

I will explain with your example: I have this model:

Whn I generate code I obtain these system files as I intended:

the problem Is that the function test, instead of calling directly the function rk4, calls a function in Subsystem.c (void Subsystem_rk4(real_T rtu_u, real_T rtu_v, real_T *rty_x, real_T *rty_y)) and that function calls the intended one (void rk4(real_T rtu_u, real_T rtu_v, B_rk4_T *localB)). With my previous method even though it had a weird name, it did not do this and the function was called directly.

As a footnote, I also tried this method with my working example (much more complex) and the generated code itself is not very good with useless variables, completely different from the one generated with my previous method. If there was a way of figuring out why the generated name is so weird it would be perfect so I have some idea how to change it.

Anyways, thank you very much for the help!

Me too facing the same Issue of Random name generation. Does any one has the solution for it?

How come no one from Mathworks can help here? This can not really be the intention!?

[Andreas Goser]

Fabian, MATLAB Answers is primarily a user-help-users forum and not a contact method to Technical Support. I saw you have contact support directly and will provide a first answer in a few minutes.

I have the same problem. Did anybody find a good solution to this problem? Still using Matlab 2017a
