Obtain matrix with YDIR reverse

5 views (last 30 days)
Hello good morning, I have a problem to see if anyone can help me.
I have an A matrix of , in the first column are the values of the X axis and in the second column the values of the Y axis, I need to get a B matrix of the same dimensions and identical positions of X and Y in which the data correspond to the process of trafficking the data of A and apply:
figure
scatter(A(:,1),A(:,2),'filled')
set(gca,'YDir','reverse')
So when I create B what is the matrix that i don't know how to create I expect to obtain the same result but without reversing the axis:
figure
scatter(B(:,1),B(:,2),'filled')
set(gca,'YDir','normal')

Since reversing the y-direction is mostly equivalent to flipping the sign:
B=[A(:,1) -A(:,2)];

Matrix A: Matrix A
And what I want to obtain when I plot B is this:
B

You can shift them by using original data range:
col2=A(:,2);
col2=min(col2)+max(col2)-col2;
B=[A(:,1) -col2];
