MATLAB: How to include a function into the main directory

directoryfunction

I've created some functions that I use often. I'm wondering if there's any way to make it so that the functions work even if they're not in the current directory. Basically it would work such as if it was one of the default functions (rand(n)).

Any help will be highly appreciated. Thanks in advance.

You can add the directory containging your function to the MATLAB search path. Try

doc pathtool

MATLAB: Directory Issue – not finding subfolder

"Any advice on how to approach this issue is appreciated."

Do not use cd.
Do not add data folders to the Search Path.
Use absolute or relative file paths.
Construct the file paths using fullfile.

Either use dir or sprintf to suit your requirements, e.g. (untested, but should get you started):

P = 'path of the root directory'
S = dir(fullfile(P,'*'));
Q = setdiff({S([S.isdir]).name},{'.','..'});
for ii = 1:numel(Q) % loop over subfolders.
    S = dir(fullfile(P,Q{ii},'*'));
    R = setdiff({S([S.isdir]).name},{'.','..'});
    for jj = 1:numel(R) % loop over subsubfolders.
        S = dir(fullfile(P,Q{ii},R{jj},'*.txt'));
        for kk = 1:numel(S) % loop over files.
            F = fullfile(P,Q{ii},R{jj},S(kk).name); % Filename
            ... process your file
        end
    end
end

MATLAB: Why these errors occurs

The directories whose paths end in \ja (like toolbox\wavelet\wavelet\ja)should not be on the MATLAB path and should not be your current directory. If they're on the MATLAB path, remove them from the path using the Path Tool. Make sure you Save the path after removing those directories from the path.
