10 May 2014 Generate "Error Correcting Output Codes (ECOC)" matrix This simple code, generates the ECOC matrix for both dense and sparse schemes. Author: Mohammad Ali Bagheri

Hi,

How I want to use this one with your ensemble toolbox?

29 May 2013 octave Generates normalized A-weigthing, -weighting, octave and one-third-octave digital filters. Author: Christophe COUVREUR

Hi,

It is true how to calculate the dBA value:

1) [B,A] = adsgn(22050);
2) Y = filter(B,A,X);
3) P = leq(Y,t); // t=number of sample
4) The result in dBA??

Thank You

Thank you for the comment.. I just concern It should be same answer for 'feat' at Approximate coefficient.. From the example you given, YES the answer are same.. when I go through the code (getmswtfeat.m) It is look like different in how to determine the last answer.. for code (getmswpfeatV00.m).. I can understand the flow.. but for the 'getmswtfeat.m', I'm confused for term 'percentENER(notZER,:) = ...', '[cfs,longs] = wdec2cl(dec,'all')',.. and I hope the final answer for 'tab_ENER' should be same as WP code... sorry to many question...

Thank You Dr Rami,

I tried the code (getmswtfeat.m (Your WT code)) and try to remove and maintain 'log1p'.. the result for 'energy' approximate coefficient are different when using the code (getmswpfeatV00.m)..

Thank you for reply..I understand now..

If I run this code (getmswpfeatV00.m) and I only took the energy at approximation part (Low pass filter part).. It is the result will be same if I'm using this code (getmswtfeat.m (Your WT code))?

One more thing, actually the code below is for what? Because you said can comment it.. If I comment this code the result is different.

I test for J=1 and comment the code below and I compare with using this code ([CA,CD] = dwt(xx,'sym8');) and took the energy for CA and CD.. and the result is same.

%% You can comment this section
JJ = J;
for i=1:J-1
T = (2^i):(2^i)+(2^i)-1;
feat(:,T) = feat(:,T)./log(JJ);
JJ=JJ-1;
end
