Hi @huili,

It's likely that the file path hasn't been added, or the file is missing, which is why MATLAB cannot recognize the MAT-file.

To resolve this:

1. Check Directory: Ensure korea5c.mat is in your current directory or on the MATLAB path.
2. Set Path: Use addpath('path_to_directory') to add the directory containing the MAT-file.
3. Load File: Use load('korea5c.mat') to load the dataset.
4. Verify File: Confirm the file exists.
5. Use Full Path: Try load('C:\full_path\korea5c.mat') if needed.

I have attached the koreas5c.mat file in the attachments from an example from this documentation page MATLAB.

You can download it, place it in an added path and try again.

info = matfile('korea5c.mat')

info = 
  matlab.io.MatFile

  Properties:
      Properties.Source: '/users/mss.system.w469v/korea5c.mat'           
    Properties.Writable: false                                           
            description: [2x64    char]                                  
                korea5c: [180x240 double]                                
               korea5cR: [1x1     map.rasterref.GeographicCellsReference]
                 source: [2x76    char]                                  

Hope this helps!
