MATLAB: Parfor problems ( add attached files)

attachedfileerrorparforpool

My code is too slow, so i tried using 'parfor' like below
parfor i = 1:26
    etatl=(i*10)+90;
    xil=etatl+3;
    for j= 1:20
        qso=j*0.00005
        qmo = 0.001-qso;
        fbt_  % this is my code for calculation
    end
end
=============================================
but i still get error, 'UndefinedFunction error in 'etatl' worker.
use addAttachedFiles(pool,files) and attach needed files. check 'parallel.Pool/addAttachedFile'.
=====
i checked 'parallel.Pool/addAttachedFile' but i still don't know how to solve the problem..

I think the problem here is that "fbt_.m" is a script file. You should convert it to a function. More in the doc about scripts and functions here: https://www.mathworks.com/help/matlab/matlab_prog/scripts-and-functions.html .
