Hi, I have a figure that contains about 10 curves. I have another figure that has only one curve. I want to math one curve figure with one of the curves in the figure that has 10 curves. Both figures have different scale.It is only the curve I want to match. Please how do I do it? Thanks
No products are associated with this question.
What does "match" exactly mean? Do you want to compare the mean value, the shape, are the curves shifted horizontally or vertically only, do they have the same mean, but different scales, or are the curves equal expect for some noise?
If only the scales (and means) differ, you can "normalize" them by dividing by the maximum absolute value (and subtracting the mean). Then "matching" could mean to find the minimum difference between the single curve and the set of curves. Now "minimum difference" must be defined also: does "distance" mean the sum of the absolute differences of all points, the maximum difference, the mean or minimal difference, the standard deviation of the differences, etc.?
