Hi, I have a blank Screen with dimensions:
Screen = 255*ones(1024,1280,3);
Where 1024 and 1280 are the height and width and 3 is the RGB component.
If I have two separate co-ordinate systems:
r1 = [randi([1 1000],1,1500)', randi([1 1000],1,1500)'];
r2 = [randi([1 1000],1,1500)', randi([1 1000],1,1500)'];
Is there a quick way (without for loop, and without using plot) to map these co-ordinates onto the Screen, with r1 being blue and r2 being red?
Below is a crude image I've made using paint to give a little more context of what I'm trying to achieve (of course with way more dots!):
Any help would be greatly appreaciated! The reason I wanted to find a quick way is because I'll be doing something like this over many iterations so was wondering if there was a fast non-for-loopy way of mapping.
For example in the next iteration I wanted to keep this Screen with the blue and red dots and then overlay a new set of blue and red dots.
