sort a matrix depending on first row

I have a matrix B

>> B

B =

      5.0000    1.0000    6.0000    3.0000
      0.6076    0.4943    0.1097    0.4754
     -0.1178   -1.4831    1.1287    1.1741
      0.6992   -1.0203   -0.2900    0.1269
      0.2696   -0.4470    1.2616   -0.6568

depending on the first rwo values I want to sort the data. i.e., my result should look like this

>> 
ans=     
      1.0000    3.0000    5.0000    6.0000
      0.4943    0.4754    0.6076    0.1097
     -1.4831    1.1741   -0.1178    1.1287
     -1.0203    0.1269    0.6992   -0.2900
     -0.4470   -0.6568    0.2696    1.2616

How to do this?

Answer 1

[Andrei Bobrov]

out = sortrows(B.',1).'

variant

[~,inx]=sort(B(1,:));
out = B(:,inx);

Hi,

Thank you very much, solved my problem

[Barrett Durtschi]

Thank you for this answer! What would I change in the statement if I wanted the first four row values?

[Bruno Luong]

out = sortrows(B(1:4,:).',1).'

Answer 2

[TAB]

[mat inx]=sort(b(1,:));
SortedMat=[b(:,inx(1)),b(:,inx(2)),b(:,inx(3)),b(:,inx(4))];
