I have two points with different coordinates point A=x,y for 1400 numbers and point B= x,y for 14000 numbers.

First: i want to connect between each value of point A an point B, Second: I want to get a new variable which contain in the first row the first value of x for point B and in the second row the first value of x for pA and apply this for all values from two poins: to make th extrapolation form this values to predicte any values from this line

please look at the attach pictuer Thank you for help

The question is still not clear. How do you want to use 19.6 million "connections" to extrapolate what or to "get new x and y axes"? Are you looking for a PCA (search this in the net)? Do you mean the convex hull of the points? I cannot imagine why creating a huge list of connections is useful. And in addition tow sets of points do not allow to "extrapolate" or "predict" anything - a substantial part of the problem has not been mentioned yet. An extrapolation requires to choose a model to describe the existing data, and a fixed component, at which the model is evaluated. Maybe you mean a line through the centers of the sets of points and you want to find the point, where this line crosses the X axis. But this is a bold guess only.

Thank you very much. you are right its too much. a friend of me fix this and made a new calculation. a regression to identify x axis from y axis to detect the cross section point with horizontal line. And present one graph to make sure that his calculation is right
