MATLAB: I want to generate a fixed percent of random points on a straight line joining two points.

MATLABstraight line

I want to generate 5 percent of the randomly generated numbers in a fixed straight line equation. For example, i have two points (x1, y1) and (x2, y2), and now i have drawn a straight line between the two points, with the help of straight line equation. Now i want 100 random numbers to be generated out of which 5 percent of those random numbers should fall in the straight line that is joined between the two points.

Best Answer

Instead of generating 100 random numbers, use "rand" to generate 5 random numbers on [0:1] and set the points to
lambda=rand(5,1);
x=x1+lambda*(x2-x1); 
y=y1+lambda*(y2-y1);
