Using a for loop, how do i make an array where the first column is the x value & the second column is the y value when extracting the x & y values from a larger, non-square matrix? I want every 20th value of x and y starting at 10 for both of them.

I dont have any code because my computer cant run the data...it needs to be processed on a super computer. Also i dont know if i should create an array or a matrix of these values, but i will want to access them later and use the as center points for drawing lines. Thank you
