问题:

I have some MATLAB functions defined in .m files and I'd like to import them into MATLAB (as in I'd like to be able to call them as I do a built-in function). How can I do this?

回答1:

You have to set the path. See here.

回答2:

If the folder just contains functions then adding the folders to the path at the start of the script will suffice.

addpath('../folder_x/');
addpath('../folder_y/');

If they are Packages, folders starting with a '+' then they also need to be imported.

import package_x.*
import package_y.*

You need to add the package folders parent to the search path.

回答3:

You should be able to put them in your ~/matlab on unix.

I'm not sure which directory matlab looks in for windows, but you should be able to figure it out by executing userpath from the matlab command line.
