I have a straight line(X1,Y1) (X2,Y2). I want to know the coordinates of all the points present on the straight line. I have another random line along the straight line. I have to calculate the Mean Squared Error between the two lines. How do i do it

"I want to know the coordinates of all the points present on the straight line"
There are infinite points between any two points on that line. How do you hope to store infinite points on your computer?

p1 = [0 0] ;
p2 = [1 2] ;
% get slope
m = (p2(2)-p1(2))/(p2(1)-p1(1)) ;
% get between points
xi = p1(1):0.01:p2(1) ;
yi = p1(2)+m*(xi-p1(1)) ;
figure
p12 = [p1 ;p2] ;
plot(p12(:,1),p12(:,2),'r')
hold on
plot(xi,yi,'.b')
