This is normal depending on what you want to do in Matlab.
If you have no script or something, change the matlab directory to the same interface, either unix directly at the command prompt ( cd C:\Users\SEU_NOME ) or with the same mouse.
Above your name is your default windows directory, but maybe use some other directory that you have created along with its path (for example C:\MEUS_TESTES\TESTE1 ).
If your simulation depends on the scripts and files you have created, transfer these files to the directory you want to run, change the directory in matlab (Matlab does this automatically depending on how you open and run the files) and start run from there. Beware of dependencies that you might have created, such as running simulations and asking to write to a specific directory or calling a file through the entire path.
One important point, Matlab automatically calls the functions of its library, but other functions or scripts that have been created must be in the same directory that is being run or in some folder that is in path of matlab.
path is a list of directories that a system will automatically search for programs.
Matlab has its own path that makes its libraries available, it can be changed in the configurations. I do not recommend to change path for anything, since its functions may take precedence over functions of the same name in the matlab library, and in the future this may cause problems.
If this has not been fixed, leave comments that I can try to see what the problem is.
