srsRAN MATALB Assertion Failed while testing

[golisrikanth1989]

Hi Team,

I wanted check this matlab based srsRAN test and following the doc below, https://docs.srsran.com/projects/project/en/latest/tutorials/source/matlab/source/index.html#installation

Using the MATLAB 2023b version. While running and test the scripts, One test getting failed and its error message is shown in below,

I was getting this issue from the ans variable in (1,1) location. I am not sure which file to change can anyone help to resolve this issue.

assertEqual failed.--> Classes do not match. Actual Class: logical Expected Class: doubleActual Value: logical 0Expected Value: 0

Hi @golisrikanth1989,
thanks for pointing this out. We haven't tested our software with R2023b, only with R2023a (and some previous versions). However, we've encountered a similar error before when going from R2022b to R2023a. The reason is that MATLAB has probably changed the default type of one of the fields inside an NR object.
Can you rerun the failed test and paste the entire output? I can't see exactly which assertion is failing - my guess is

            obj.assertEqual(pusch.TransformPrecoding, 0, 'Wrong transform precoding.');

on line 133 of unitTests/CheckAnalyzers.m. If so, just change it to

            obj.assertEqual(double(pusch.TransformPrecoding), 0, 'Wrong transform precoding.');

and it should work. We'll fix this in the next release.

Hi @dvdgrgrtt,

Thanks for the response,

Now its getting passed with all test, here is the output,
