Access Denied to a folder created by the script

Hello Everyone-

I am not an expert on Matlab but I am trying to validate some theoritical results using it as an interface of OpenEMS. I keep getting an error of denied access to a folder created by the script itself. I have tried running Matlab as an Admin and deletingt he folder and renaming it and even changing directories. I am kind of stuck and confused about the reason behind this error. Please see part of the code below and error. Thank you very much!

this is the part of the code in which I create the fodler:

%% Path

Sim_Name = ['Sim_DOA_', num2str(a), 'deg']; % e.g., Sim_DOA_-60deg

Sim_Folder = fullfile('C:\Users\HP\Documents\MATLAB\Simulations', Sim_Name);

Sim_CSX = 'geometry.xml'; % geometry file name

% Create the folder if it doesn't exist

if ~exist(Sim_Folder, 'dir')

mkdir(Sim_Folder);

end

WriteOpenEMS(Sim_Folder, FDTD, CSX);

RunOpenEMS(Sim_Folder, Sim_CSX);

and this is the error:

Error using xmlwrite>xmlWriteHelper (line 152)

Java exception occurred:

java.io.FileNotFoundException: C:\Users\HP\Documents\MATLAB\Simulations\Sim_DOA_-60deg (Access is

denied)

You create

C:\Users\HP\Documents\MATLAB\Simulations\Sim_DOA_-60deg

as a folder.

But

WriteOpenEMS(Sim_Folder, FDTD, CSX);

assumes that

C:\Users\HP\Documents\MATLAB\Simulations\Sim_DOA_-60deg

is a filename.

So you try to write to a folder instead of a file which gives an error.

At least that's what I suspect is the problem.
