Accepted answer

x=rand(1,100)*5 y=rand(1,100)*5 scatter(x,y)

or

a=rand(2,100)*5 scatter(a(1,:),a(2,:))

Here's an alternate interpretation, if you want 100 locations in a matrix set to some value, such as 1.

% Randomly place a value of 1 at 100 locations. m=10; % Whatever % Make a "canvass" of all zeroes. theArray = zeros(5*m); % Get 100 linear indices randomly located linearIndices = randperm(numel(theArray), 100); % Make those 100 locations have a value of 1: theArray(linearIndices) = 1;

How to generate say 10 out of 100 random points on a straight line joining two points? I have two points let, (x1,y1) and (x2,y2). These two points are joined by a straight line. Now i want to generate, 10 points out of 100 random points on the straight line. Let the boundary be a square, with side length 50m
