When I apply wmulden to an array A I obtain an array B with denoised signal:
level = 4;
wname = 'sym2';
tptr = 'heursure';
sorh = 's';
mode = 'asym';
SCAL ='mln';
npc_app = 'none';
npc_fin = 'none';
[B, npc, nestco] = wmulden(A, level,wname,'mode',mode, npc_app, ...
npc_fin, tptr, sorh);
If I change only one of all the data in array A the calculated array B is totally different in every single data.
[n,m]=size(A);
A(n-100,1:m)=A(n-100,1:m)+rand(1,1:m)*0.1;
[B2, npc, nestco] = wmulden(A, level,wname,'mode',mode, npc_app, ...
npc_fin, tptr, sorh);
I need :
B(1:n-101,1:m) = B2(1:n-101,1:m) && B(1:n-99,1:m) = B2(1:n-99,1:m)
and
B2(1:n-100,1:m)
is correctly denoised.
I ask if is possible to use the parameters calculated previously to apply them with wmulden only to the changed data preserving the unchanged data.
Thanks!
