generating 4 d tuple

I have 2x25 matrix that describes x,y cordinates, I want to draw circles with radious r1 and r2 and adress each compination ! in other words :

i want to address (x1,y1,r1,r1), (x1,y1,r1,r2),,(x1,y1,r2,r2) to figure out the cases where there is an overlap or not. how to do that in matlab ?

Matlab doesn't have a tuple class, but uses arrays.

If I'm understanding you, you want to end up with a 4x100 array. The most straight forward approach is probably to start with your 2x25, then build it out using a For loop.

Thanks Joe, actually I should end up with 25 x25x2x2 to be precise , but i might create a 4d matrix with for loop as you mentioned!
