Save data from for-loop and their use

1 view (last 30 days)
Hello,
I have the following problems. I have matrices: SatTrDatax_Norm (4X200) and SatTrDatay_Norm (4x50). I want to apply wavelet decomposition(wavedec) to each line separately. Next, I try to save the results to new matrices (C1,L1,C2,L2). Use for-loop but save the last value in C1,L1,C2,L2.How do I store all values resulting from the for-loop? The second problem concerns reconstruction (wrcoeff). The matrices C1,L1,C2,L2 according to the documentation must be a vector. How is this going to be done? Your help is invaluable.
for i=1:4
[C1,L1]=wavedec(SatTrDatax_Norm(i,:),3,'db1');
[C2,L2]=wavedec(SatTrDatay(i,:),3,'db1');
end
AppTrDxNorm_Sat=wrcoef('a',C1,L1,'db5',3);
D1TrDxNorm_Sat=wrcoef('d',C1,L1,'db5',1);
D2TrDxNorm_Sat=wrcoef('d',C1,L1,'db5',2);
D3TrDxNorm_Sat=wrcoef('d',C1,L1,'db5',3);
%
AppTrDySat=wrcoef('a',C2,L2,'db5',3);
D1TrDySat=wrcoef('d',C2,L2,'db5',1);
D2TrDySat=wrcoef('d',C2,L2,'db5',2);
D3TrDySat=wrcoef('d',C2,L2,'db5',3);

You just need to index your output and then reference the appropraite index
for i=1:4
[C1(i,:),L1(i,:)]=wavedec(SatTrDatax_Norm(i,:),3,'db1');
[C2(i,:),L2(i,:)]=wavedec(SatTrDatay(i,:),3,'db1');
end

It is OK. There was an error in the calculations. Now everything works. Thank you very much for your valuable help !!!
