if directory exist matlab

To check if a directory exists in MATLAB, you can use the exist function. Here's an example:

directory = 'path/to/directory';
if exist(directory, 'dir')
    disp('Directory exists');
    disp('Directory does not exist');

Replace 'path/to/directory' with the actual path to the directory you want to check. The exist function returns 7 if the directory exists and 0 if it doesn't [[SOURCE 1]].
