07 May 2013	Ellipsoid fit Fits an ellipsoid to data using linear least squares.	kostas	I used your code but the results are not correct with my data. The eigen values are very big. Should you normalise the Covariance matrix? I would also want to ask how did you derive from the 9 parameters of ellipsoid, the covariance matrix, center etc.. which book, notes did u use?

06 May 2013	Ellipsoid fit Fits an ellipsoid to data using linear least squares.	Liang Sun	If the ellipsoid passes through the origin (0,0,0), how can the default equation "Ax^2 + By^2 + Cz^2 + 2Dxy + 2Exz + 2Fyz + 2Gx + 2Hy + 2Iz = 1" represent that? Thanks!	Comment only
29 Apr 2013	addaxis Add multiple y-axes to plots. zoomable with zoom modification.	Tobias	Great function! For those of you who can not figure out how to make the zooming and panning working, here is a solution: 1. Open the addaxis.m and find these lines: "% plot in new axis to get the automatically generated ylimits hplt = plot(varargin{:});" 2. Add the following code after "hplt = plot(varargin{:});" : h_new = zoom; set(h_new,'ActionPostCallback',@postcallbackzoom); set(h_new,'ActionPreCallback',@precallbackzoom); set(h_new,'Enable','on'); set(h_new,'Enable','off'); h_new=pan; set(h_new,'ActionPostCallback',@postcallbackpan); set(h_new,'ActionPreCallback',@precallbackpan); set(h_new,'Enable','on'); set(h_new,'Enable','off'); 3. Goto the end of 'addaxis.m' and add the followong code: function precallbackzoom(obj,evd) old(1:2) = get(evd.Axes,'YLim'); old(3) = evd.Axes; ax = findall(obj,'type','axes'); ax = ax(ax~=evd.Axes); leg = findall(obj,'Tag','legend'); if(~isempty(leg)) ax = ax(ax~=findall(obj,'Tag','legend')); end for i=1:length(ax) old(i+1,1:2)=get(ax(i),'YLim'); old(i+1,3)=ax(i); end setappdata(obj,'OldAxes',old); function postcallbackzoom(obj,evd) old = getappdata(obj,'OldAxes'); new(1:2) = get(evd.Axes,'YLim'); d=(old(1,2)-old(1,1)); d1=(new(1)-old(1,1))/d; d2=(new(2)-old(1,2))/d; s=size(old); for i=2:s(1) d=old(i,2)-old(i,1); set(old(i,3),'YLim',[ (old(i,1))+dd1 , (old(i,2))+dd2]); end function postcallbackpan(obj,evd) set(obj,'WindowButtonMotionFcn',''); function precallbackpan(obj,evd) ax = findall(obj,'type','axes'); ax = ax(ax~=evd.Axes); leg = findall(obj,'Tag','legend'); if(~isempty(leg)) ax = ax(ax~=findall(obj,'Tag','legend')); end OldY=[get(gca,'YLim'),ax']; set(obj,'WindowButtonMotionFcn',{@CallbackPan,obj}); setappdata(obj,'OldY',OldY); function CallbackPan(hObject, eventdata, handles) old = getappdata(hObject,'OldY'); new(1:2) = get(gca,'YLim'); d=(new(1)-old(1))/(new(2)-new(1)); for i=3:length(old) d1 = get(old(i),'YLim'); d1_= d1(2)-d1(1); set(old(i),'YLim',d1+d*d1_); end old(1:2)=new; setappdata(hObject,'OldY',old); 4. That's it. Save your addaxis.m and enjoy zooming and panning. By the way you don't have the use the new zoom-functions (zoom modifications for R11.1 and R14SP2) provided with this function. Tested on Matlab 2012b.	5
06 Feb 2013	addaxis Add multiple y-axes to plots. zoomable with zoom modification.	martijn	GREAT! but does somebody have the solution to the zoomproblem. The readme does not apply to me, since I use Matlab 2012. If you know the solution, can you mail me? or drop it here? martijnvanhooff89@gmail.com	5
