How to realize the variable number of input parameters

we usually introduce two endpoints (x1,y1) and (x2,y2) for a line

N = 50;
prompt     = transpose({'X1:', 'Y1:', 'X2:', 'Y2:'});
title_text = 'Input X and Y';
point      = inputdlg(prompt, title_text,[1,length(title_text) + N]);

However, if there are variable number of lines, which means we need to input variable number of endpoints

For example, num_line (i.e. number of line) = n (n=1,2,3,4...), so we need to input 2*n endpoints for 'n' lines

Is there have any method to do it?

Thanks for your help!

How about input two arrays of coordinates? x=[1,2,3,4], y=[5,6,7,8] for example? Your function takes input of two arrays. It doesn't matter how long the arrays are.
