Holder exponent time consuming

%Calculating standard Deviations for HE
%Calculating holder exponent values
HE=zeros(131072,2);
HE(:,1) = estimOSC1DH(denoised(1:131072,1),2.1,0.0001,0.43);
HE(:,2) = estimOSC1DH(denoised(1:131072,2),2.1,0.0001,0.43);

for the coding of holder exponent, It took ages to finish the calculation with 131072 number of points. It tooke for 2 hours to solve that. Any idea how to reduce the calculation time ?

What is estimOSC1DH?

My Matlab doesn't suggest I need some toolbox when I type it in, it just says it doesn't exist, so I assume it isn't a Matlab toolbox function?
