25 Mar 2009 Find Optimal Kernel Find optimal causal filter kernel that convolves with one time series to approximate another Author: Matthew Nelson

xcov is available in matlab's signal processing toolbox. I'm sorry if that wasn't clear before. I've adjusted the online page to reflect that.

12 Mar 2010 Huynh-Feldt epsilon general procedure Calc. the Huynh-Feldt epsilon for any arbitrary combination of between and within subject factors Author: Matthew Nelson Yoni

This seems useful, especially with allowing the arbitrary numbers of both kinds of factors. But what functions would you use to get the actual F values from data that are arranged in the same way?
05 Oct 2009 Huynh-Feldt epsilon general procedure Calc. the Huynh-Feldt epsilon for any arbitrary combination of between and within subject factors Author: Matthew Nelson Kathrin

thank you! very flexible and easy to use for repeated measures anova. but it would be even more helpful if there was a little statistic (like mauchly's test on sphericity) specifying if one needs to adjust the degrees of freedoms with the computed epsilon estimates.

I just used your code and it is good commented. Does what I wanted it to do ;)

% Sorry for the typos above...

newInSig=[InSig; InSig];
newOutSig=[OutSig; OutSig];
 
for i = 1:r
   Cxy(i,1)=InSig' * newOutSig(i+r-1,:);
   Cxx(i,1)=InSig' * newInSig(i+r-1,:);
end
Cxy=Cxy(2:MaxnLags+1, :);
Cxx=Cxx(1:MaxnLags, :);
Cxxmat=toeplitz(Cxx);
 
k= (Cxxmat^-1)*Cxy;

% Without access to the Signal Processing Toolbox, it's difficult to % say for sure, but I suspect the following code would allow you to % run this routine without calling the xcov() function.

newInSig=[InSig; InSig];
newOutSig=[OutSig;outSig];

for i = 1:r
   Cxy(i,1)=InSig' * newOutSig(i+r-1,:);
   Cxx(i,1)=InSig' * newOutSig(i+r-1,:);
end
Cxy=Cxy(2:MaxnLags+1, :);
Cxx=Cxx(1:MaxnLags, :);
Cxxmat=toeplitz(Cxx);

k= (Cxxmat^-1)*Cxy;
