matlab results grouped question

How can i have in results all the first results and all the second results regrouped?

 0.3151
   -0.3904

    0.3412
   -0.3416

    0.3581
   -0.2836

How you got the results, share code?

I've solved...

I've a problem...

after this code, i obtain 14 2x2 matrix, how can i calculate the inverse of every matrix?

OA=1.42
AB=4.3
BO=3.33
OO=6
alfa=[19.7000,   10.2615,    0.8231,   -8.6154,  -18.0538,  -27.4923,  -36.9308,  -46.3692,  -55.8077,  -65.2462,  -74.6846,  -84.1231,  -93.5615, -103.0000];
beta= [37.3648, 40.5764, 43.6511, 46.4267, 48.7411, 50.4573, 51.4816, 51.7706, 51.3269, 50.1884, 48.4165, 46.0853, 43.2749, 40.0669];
gamma= [-68.0355, -66.333, -63.8261, -60.6513, -56.9882, -53.0279, -48.9467, -44.8871, -40.9515, -37.2048, -33.6824, -30.3996, -27.3598, -24.5623]
for i = 1:14
J = [AB*sind(beta(i)) BO*sind(gamma(i)); AB*cosd(beta(i)) BO*cosd(gamma(i))]

end

Hi,

i assume you have the results in a form of:

res1 = [0.3151; -0.3904]
res2 = [0.3412; -0.3416]
res3 = [0.3581; -0.2836]

which looks like in your question:

res1 =

   0.315100000000000
  -0.390400000000000


res2 =

   0.341200000000000
  -0.341600000000000


res3 =

   0.358100000000000
  -0.283600000000000

Then you can do:

res = reshape([res1; res2; res3],2,[]);
group1 = res(1,:)'
group2 = res(2,:)'

which results in:

group1 =

   0.315100000000000
   0.341200000000000
   0.358100000000000


group2 =

  -0.390400000000000
  -0.341600000000000
  -0.283600000000000

Check the reshape function - it is very useful.

Best regards

No, unfortunately i've this;

   0.2187
   -0.3606

    0.2738
   -0.3349

    0.3203
   -0.3092

    0.3581
   -0.2836

they are not "named " (res1, res2)

How can i do to group together the first rows, and together the second rows?
