How to add a folder permanently to matlab path?

I am using addpath to add specified folders to matlab path, but it removes the folders from the matlab path everytime the application closes. I want to add that particular folder permanently to matlab path, so that I don't have to add it again everytime i run the application. How can it be done??

Any help is appreciated.

The persistence of the path has been a problem for many releases. Savepath and the save button in the setpath toolbar utility have not worked correctly in every release for many years.

1) If you're using Windows you could try using the MATLABPATH environment variable.

2) You could edit the pathdef.m file even though this is not recommended.

3) I modify the startup.m file to add 64 folders to the search path. The file kpath.mat contains a structure with a single variable that is a character vector of the full path to each of 64 folders that I want to add to the path separated by ';'.

p = load('kpath.mat');
   addpath(path(p.kpath,path));
   clearvars p;

You can put the addpath statement to startup.m

Heres how to create startup.m http://www.mathworks.com/help/matlab/ref/startup.html?searchHighlight=startup.m

This method works best and I have adopted it. Using it makes it unnecessary to maunally add the desired paths and folders at the beginning of a MATLAB session, thereby saving a step.

I am also using this method for my user written functions.

Best answer, thanks! Just to remind that all the folder name should not have space between or it could get wrong

On Matlab's toolstrip, you may find the option "Set Path" which allows to select one directory (or also its subfolders) and save it permanently to Matlab's "search path".

[Roy Axford]

This solution has merit in that it takes advantage of the tool strip and it works. But it is not permenant. It must be repeated each time I restart MATLAB.

I used the solution proposed by Luis Fresco. It worked (I didn't need to do it every time I restarted MatLab). Into the default search path I added a new folder with some functions in it. I put "Add with subfolders", selected the main folder and when a new window pop-up, just accept that.

I wrote a script in the main folder which uses a function into the subfolder, and it worked just fine. I restarted MatLab to check if the solution was permanently, and it is.
