I know how to import a specific file, but what if matlab has two folders set as pathways to check of which both have same filename and filetype, identical.

example: "example.txt"

and their in both folders, and if you importdata('example.txt');

I assume that will just select one of them depending on whichever it encounters first.

Is there a way to select the file through some function I am unaware of?

Cheers, Shane

在 MATLAB Online 中打开

Use fullfile() to specify the folder and full file name (path + base file name + extension) of the one you want to import.

fullFileName = fullfile(folder1, 'example.txt');
if exist(fullFileName, 'file')
  csvread(fullFileName);
else
  message = sprintf('Warning: %s does not exist', fullFileName);
  uiwait(warndlg(message));
end
