Error: invalid ELF header - Trying to call a Matlab function from COMSOL

Steps to get the error:
- From Ubuntu, I do start COMSOL as:
comsol -mlroot /usr/local/MATLAB/R2019b -forcegcc
- Within COMSOL, under the "Global definitions" node,
Functions = "/home/miguel/Desktop/PCE proyecto/code/seedDispersal/seed_v_w.m".
Funtion name = seed_v_w
Arguments = v_e, beta_p, lambda_p, v_w_X0 -> (they are constants and they have all been declared as COMSOL Variables)
- basically the MATLAB function is : ( files attached for complete code)
function Xt = seedvw(ve, betap, lambdap, X0) ... ( stuff here) Xt = (....calculated value) end
- When I click on the COMSOL "Compute", the following error appears:
- Feature: Compile Equations: Time Dependent (sol1/st1) Error in multiphysics compilation. Failed to load library.
- Library: /home/miguel/Desktop/PCE proyecto/code/seedDispersal/seed_v_w.m
- Error: /home/miguel/Desktop/PCE proyecto/code/seedDispersal/seed_v_w.m: invalid ELF header
Thank you in advance !

Hi Miguel
The most likely reason for seing this error message is that something went wrong with the installation of Comsol and some of the files were corrupted.
Another guess would be that you are using a combination of Ubuntu version, Matlab version and Comsol version that is not supported.
