Hello, greetings to all. I was wondering if anyone would know if there is a function that receiving a data set like this small example:
X = [2 4 8];
Y= [2 2 4];
Could convert Y-axis data to become:
X = [2 4 8];
Y= [4 4 2];
This example is very simple but the real one has much more points, it is not something as simple as assigning the minimum to the maximum and vice versa. Thank you in advance.

@Jan Another way to explain it would be to try to obtain the values of the Y-axis based on the ordinary axes X,Y when the representation of these axes is made using:
figure;
scatter(X,Y,'filled');
set(gca,'YDir','reverse');

If I understand correctly, you want to know what the y-coordinates would be if the y axis were flipped but the datapoints stayed in their original positions within the axes. That raises a red flag to me. If you could explain why you want to do this or how you plan to use the data, perhaps we could suggesting something more eifficient and sound. The problem is, y axis limits could change so it's not just a matter of flipping the data vertically around some reflection point.

I don't get the question as well.
What result do you expect on the following arrays:
X = [2 4 8 4 2 56 78];
Y= [2 2 4 11 75 12 5];
You need to explain how variables are related.
