How to locate all sl_customization files on the MATLAB path?

In MATLAB versions up to R2019b I was able to use

which -all sl_customization

to locate all sl_customization.m and sl_customization.p files on the MATAB search path. That doesn't work anymore in newer versions.

Is there a new way to get this information?

[Michael]

I tried this with R2022b and it still works.

[Ralf]

Thank you @Michael. Das ist seltsam. Bei mir und meinen Kollegen wird in R2022b nichts angezeigt. Siehe Bild.

You could change the current folder into a directory where such an "sl_custiomization" file should be located and try the command

which -all sl_customization

again. Then you should get at least one result. If this works well you have a problem with the MATLAB search path.

[Ralf]

@Michael: That works.

However, most of my colleagues have the same issue in R2022b, but not all of them. In addition, when working in a Simulink project, the command lists all sl_customization files in the project hierarchy.

In R2019b, the command

which -all sl_customization

shows always all occurances of sl_customization files.

It seems that all the sl_customization files from earlier MATLAB versions vanished in newer version. That's why the output of

which -all sl_customization

seems to be correct.

That's why I'll close this question.

1) The official doc for which indates that "which -all" displays the paths to all items on the MATLAB path with the requested name, as well as any files in special folders that have been implicitly added to the path.

2) In R2022b, files with name including "sl_customization" (m or p files) can be found with Windows Explorer in MATLAB root folder as shown below. And none of the pathstr are members of MATLAB path as you can find with the script below.

str2test_R2022b = [
    "C:\Program Files\MATLAB\R2022b\examples\slrequirements\main\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\toolbox\rtw\rtwdemos\crl_demo\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\toolbox\qualkits\iec\ecoder\tests\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\toolbox\rtw\rtwdemos\pil_demo\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\toolbox\coder\advisor\examples\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\resources\Sldv\en\ModelAdvisor\sl_customization.xml"
    "C:\Program Files\MATLAB\R2022b\toolbox\rtw\rtwdemos\examplePilF28335\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\examples\ecoder\main\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\examples\slcheck\main\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\examples\systemcomposer\main\sl_customization.m"];

is_in_path = false(1, length(str2test_R2022b));
for i = 1:length(str2test_R2022b)
    [pathstr, name, ext] = fileparts(str2test_R2022b(i));
    is_in_path(i) = contains(lower(path), lower(pathstr{1}));
end

is_in_path =

1×10 logical array

0 0 0 0 0 0 0 0 0 0

3) On the other hand in R2019b, files with name including "sl_customization" (m or p files) can be found with Windows Explorer in MATLAB root folder as shown below. And 23 of them are included in the MATLAB path. This is what is shown in "which -all".

str2test_R2019b = [
    "C:\Program Files\MATLAB\R2019b\toolbox\autoblks\autoblksutilities\sl_customization.p"

Thank you very much for your very comprehensive answer. That makes sense to me.

Answer 2

[Ralf]

It seems that all the sl_customization files from earlier MATLAB versions vanished in newer version. That's why the output of

which -all sl_customization

seems to be correct.

That's why I'll close this question.
