Hi, i wanted to minimize my code and i tried this

clc;
clear all;
close all;
load('C:\Users\del.dell-PC\pfe\base de donnée\patient avec crise\chb01_21_edfm.mat')
Fs=256;
result=cell(23,1);
 d1=designfilt('lowpassfir','PassbandFrequency',0.45,'StopbandFrequency',0.5,'PassbandRipple',3,'StopbandAttenuation',60,'DesignMethod','equiripple');
for n=1:23
    deriv=(val(n,:))/2.559375;
    t=(0:length(deriv)-1)/Fs;
    result{n} = filtfilt(d1,deriv);
    moyenne{n}=mean(result{n},2); 
    variance{n} = std(result{n},[], 2);
    Maximale{n}= max(result{n},[],2);
    Minimale{n} =  min(result{n},[],2);
    [c,l]=wavedec(result{n},4,'db4');
    [cd1,cd2,cd3,cd4]=detcoef(c,l,[1,2,3,4]);
    cA4=appcoef(c,l,'db4',4);
    [Ea,Ed]=wenergy(c,l)
   end
  [a,b,z,d,e,f,g,h,i,j,k,ll,m,n,o,p,q,r,s,x,u,v,w]=result{:};

But i dont know how to make the result of "Wenergy(c,l)" like

moyenne{n}=mean(result{n},2)

i tried this

energie{n}= [Ea,Ed](result{n},[],2);

but i got this error message "Unbalanced or unexpected parenthesis or bracket".

Can anyone help me please?

I am not at all clear what you are trying to do. Maybe

      [Ea, Ed] = wenergy(c,l);
      energie{n} = {Ea, Ed};

And as you can see it's too long so how can i reduce it?
