%-------------------------------------------------- % Synopsis: bite-size replacement for % [gparm,Q] = gmix_step(gparm,xn); % The following code is equivalent to one call to % gmix_step. The numerical behavior is identical. %-------------------------------------------------- % gparm = init_gmix( .....); for iteration=1:10, % initialize accumulators to zero % at start of each iteration newmean=[]; newvar=[]; atot=zeros(nmode,1); for i=1:nmode, newmean{i}=zeros(dim,1); newvar{i}=zeros(dim,dim); end; qtot=0; % Loop over 1000 bite-size pieces for i=1 : 1000, x = ... % get new data matrix [newmean,newvar,atot,qtot] = ... gmix_accum(gparm,x,newmean,newvar,atot,qtot); end; % finalize the iteration gparm = gmix_norm(gparm,newmean,newvar,atot); end;
