Hello,
I have the following. I have a matrix W (2Χ50) and I make the scatter plot for each of its row, that is,
scatter(W(1,:),W(2,:))
The first point in the sctter plot corresponds to W (1,33), the second to the point W (2,5) and so on. How can I put these points (of the scatter plot) in a new matrix in the order they appear in the scatter plot?

Assuming you mean by the first point, second point, etc in the scatter plot their order of appearance from left to right (along the x axis of the plot) you could do this
[~,idx] = sort(W(1,:))
Wnew = W(:,idx)
