BEST REGARDED.
CODE:
m = 1;
for n = 1:length(sol.xs)
possibleSol(1,m) = double(sol.xs(n));
possibleSol(2,m) = double(sol.ys(n));
possibleSol(3,m) = double(sol.zs(n))
m=m+1;
end

What is it you don't understand?
  • How a for loop works
  • How to assign results to specific array elements using indexing
  • How to extract a value from a variable using indexing
  • what the function double is doing?
If you understand each of those, you can figure out what the loop is doing on your own.

The values are changing because the indexing inside the for loop is telling it where to place the values.
I'm going to direct you to an interactive tutorial so you can learn and get some practice with the concept. See Ch 5 of MATLAB Onramp. If you need a little more explanation and practice with for loops, check out Ch 13.3 as well.
