Hi.

I have two areas.

How can I obtain the difference between these two?

How can I then minimize the difference by translating the second area?

Or even better, how can I display the difference between areas as a funcion of the amont of translation done to the second area?

Code and data would be helpful.

Sorry but what do you mean by code and data? :S

在 MATLAB Online 中打开

If you just want to align those two profiles using angle values, then I would use findpeaks() on both and look at their differences.

% angle1, angle2 are arrays 
[~,peaklocs1] = findpeaks(angle1); % add options such as "MinPeakDistance" and others as necessary
[~,peaklocs2] = findpeaks(angle2);
if peaklocs2(1)>peaklocs1(1)
    alignment = peaklocs2(1) - peaklocs1(1) 
else
    alignment = peaklocs1(1) - peaklocs2(1)
end
