i can generate random point within a specific area
like this
x=rand(1,100)*5
y=rand(1,100)*5
scatter(x,y)
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/666990/image.jpeg)
but i want each point generated within x<1 & y<1
must not be less than 0.05 near the pervous generated points. so no interaction between each point generated.
is it any fucntion can do thing like that?

Another idea is to generate a chequerboard, and then pick a random point inside all the black (or all the white) squares.
[x,y]=ndgrid((0:2:19)/20);
x=x(:)+rand(size(x(:)))*0.05;
y=y(:)+rand(size(y(:)))*0.05;
scatter(x,y)

I see two possible simple alternatives--
- Just use rejection technique to remove those within the prescribed distance metric(*), or
- Generate a regular grid at prescribed distance beginning at a random point; then make a random selection of N of those points.
(*) Is this global or, just as the Q? is worded, successive realizations; could still be R<Dmin between new point and some prior point earlier than the previous?
