MATLAB: How to add all subfolders in the matlab path

path subfolder

For example, my matlab folder 'current_use' is under the directory user/example/matlab/current_use and under 'current_use' folder there are 6 subfolders and each contains data files I need to test, i.e., my matlab script under folder 'current_use' will call all data under the subfolders which are inside folder 'current_use'

What I am doing now is each time tell matlab the path of each my subfolder, i.e., inside my script I have a comment to tell matlab to look the path 'user/example/matlab/current_use'.

It works. However, now I need to upload my code to the school server to run it. But after I upload everything onto school server, the path 'user/example/matlab/current_use' will no longer by correct. i.e., the part 'user/example/matlab/' is changed.

So I am wondering, is there a way that I can let matlab to add all subfolders under current folder without tell it where is the current folder? or, is there a comment that matlab can use to obtain the path for the current folder?

Thank you!

This should work regardless if your current folder is the one that contains your m-file, or not.

% Determine where your m-file's folder is.
folder = fileparts(which(mfilename)); 
% Add that folder plus all subfolders to the path.
addpath(genpath(folder));

MATLAB: Addpath from a different subfolder of the same parent directory

Data folder should never be added to the search path. It's dangerous (you may change what functions are in scope) and there's no need to anyway.

All matlab IO functions accept full paths of data file for import/export. It's much better to specify the full path of files. That way they can be anywhere you want, even on a network folder.

So, instead of something like:

%code that relies on the folder where mydatafile.txt resides to be on the path or be the current folder
data = csvread('mydatafile.txt');  %actual function used for importing is irrelevant

use

%code that works regardless of location of folder. Doesn't need to be on the path or be the current folder
folder = 'C:\somewhere\somefolder';  %location of mydatafile.txt. Could even be remote
data = csvread(fullfile(folder, 'mydatafile.txt'));

MATLAB: Unable to add S-function to MATLAB path when using “addpath”

The commands you listed will not add the 'examples' folder located under 'apps' to the MATLAB path. This is because MATLAB R2016a does not implicitly add the path of the present working directory to the string arguments in "addpath", especially when you're trying to add subfolders. The commands you can use instead are as follows:

addpath(genpath([pwd '/apps/examples']));

addpath([pwd '/lib']);

addpath(genpath([pwd '/robots']));

Please note that in MATLAB R2016b, "addpath" implicitly adds the path of the present working directory. Therefore, the original commands would work in MATLAB R2016b.
