For my data, how should I edit it with this program?

clear all
clc
n=input('Enter no. of points ');
w=input('Press 1 for entry through mouse or 2 for keyboard repectively-->');
n1=n-1;
if w==1
    axis([0 100 0 100])
    [p]=ginput(n);
end
if w==2
    [p]=input('Enter co-odinates of points within brackets ->[x1 y1;x2 y2;x3 y3;...;xn yn] ');
end
for i=0:1:n1
    % for calculating (x!/(y!(x-y)!)) values
    sigma(i+1)=factorial(n1)/(factorial(i)*factorial(n1-i)); 
end
l=[];
UB=[];
for u=0:0.002:1
    for d=1:n
        UB(d)=sigma(d)*((1-u)^(n-d))*(u^(d-1));
    end
    l=cat(1,l,UB); %catenation
end
P=l*p;
line(P(:,1),P(:,2))
line(p(:,1),p(:,2))
