Hi PA,
folder_name = "folder";
mkdir(folder_name);
Now all that is needed is to fetch the data from the excel sheet. This can be done using functions like readtable function or you can also use the GUI Import data from Home > Import Data and then opening the Excel Sheet over there.
Once you load the matrix data, convert it from a 4x4 matrix to a 1x16 vector using the reshape method. Then all thats left to be done is to loop over the vector and create a folder with name corresponding to the value at the vector index:
folder_matrix; % this you have imported from the excel sheet as a 4x4 matrix. Make sure its string
folder_vector = reshape(folder_matrix,[1,16]);
for i = 1:numel(folder_vector)
mkdir(folder_vector(i));
end
