+function files = recursive_dir(rootDir, pattern, excludeDirs)
+%RECURSIVE_DIR Recursively search for files matching a pattern, excluding specified directories.
+%   FILES = RECURSIVE_DIR(ROOTDIR, PATTERN, EXCLUDEDIRS) searches for files
+%   matching PATTERN within ROOTDIR and all its subdirectories, excluding
+%   directories listed in EXCLUDEDIRS.
+%
+%   Inputs:
+%       ROOTDIR    - A string specifying the root directory to start the search.
+%       PATTERN    - A string specifying the file pattern to match (e.g., '*.avi').
+%       EXCLUDEDIRS - A cell array of strings specifying folder names to exclude
+%                    from the search (e.g., {'.phy', 'temp'}).
+%
+%   Output:
+%       FILES      - A cell array of strings containing the full paths to all
+%                    matching files.
+%
+%   Example:
+%       % Find all .avi files in 'U:\data\hpc_ctx_project', excluding '.phy' folders
+%       files = recursive_dir('U:\data\hpc_ctx_project', '*.avi', {'.phy'});
+%
+%   See also DIR, FULLFILE.
+
+
+% Initialize the list of files
+files = [];
+
+% Get the list of files and folders in the current directory
+dirData = dir(fullfile(rootDir, pattern));
+
+% Filter out directories from the list
+dirData = dirData(~[dirData.isdir]);
+
+% Add the full path to the files
+files = [files; fullfile({dirData.folder}, {dirData.name})'];
+
+% Get the list of subdirectories
+subDirs = dir(rootDir);
+subDirs = subDirs([subDirs.isdir] & ~ismember({subDirs.name}, {'.', '..'}));
+
+% Recursively call this function on each subdirectory, excluding specified folders
+for i = 1:length(subDirs)
+    subDirPath = fullfile(rootDir, subDirs(i).name);
+
+    % Skip excluded directories
+    if ~any(strcmp(subDirs(i).name, excludeDirs))
+        files = [files; recursive_dir(subDirPath, pattern, excludeDirs)];
+    end
