Hi all,
can anyone help me how to open mat file in MATLAB.
so that i can change some data.
i used this script as below
folder = 'C:\Users\Akmal\Downloads\NUKDOS_code\NUKDOS EXE'; % You specify this!
fullMatFileName = fullfile(folder, 'Murrat_Mustermann_1223_Case.mat')
if ~exist(fullMatFileName, 'file')
message = sprintf('%s does not exist', fullMatFileName);
uiwait(warndlg(message));
else
s = load(fullMatFileName);
end
but error pop up below
Warning: Variable 'controller' originally saved as a dataProvider cannot be instantiated as an
object and will be read in as a uint32.

You need to add the class dataProvider to the MATLAB path before you load the file, if you need to load variable controller .
If you do not need variable controller then ignore the message, as it is a warning rather than an error.

No, just add the directory to your MATLAB path.
