if flag==2 flag=3;
[c,l]=wavedec(nfile,8,'db8');
ca1=appcoef(c,l,'db8',1);
ca2=appcoef(c,l,'db8',2);
ca3=appcoef(c,l,'db8',3);
ca4=appcoef(c,l,'db8',4);
figure(2),plot(ca1,'-k'),title('Cofficients of Signal At l Level Decomposition')
figure(3),plot(ca2,'-k'),title('Cofficients of Signal At 2 Level Decomposition')
figure(4),plot(ca3,'-k'),title('Cofficients of Signal At 3 Level Decomposition')
figure(5),plot(ca4,'-r'),title('Cofficients of Signal At 4 Level Decomposition')
flag=3 ;
