I want matlab to return all the elements of p2 at rows r columns c, I tried p2(r,c), but that doesn't give me the right answer.
p2 =
0.1500 0.1500
0.4804 0.4804
0.5098 0.5098
0.0498 0.0498

3.8487 3.8487
4.9765 4.9765
8.3789 8.3789

r =

I should be getting this:
0.5098
1.092
2.0219
2.9643
3.8808
4.9765
0.5098
