    Dear Sir,

    I am using 5GLLSimulator_v1.1 with MATLAB_R2017b, facing below error while running main.m under different scenarios.

    Please check and suggest way forward.

    Thanks and Regards,

    Dear Ankit Saxena,

    this issue is related to the compiled mex files. The solution is to compile the mex files yourself from the included source. Please consider the procedure as described here:

    Running files

    Let us know, in case you encounter further problems.

    best
    Stefan
