MATLAB: Making answer into array

for loopmatrix array

How can I concatenate my answers from a for-loop into an array. consider this example:
a=[2 1 3 1 
   1 4 1 5 
   6 7 1 1 
   8 1 9 1];
for i=(1:4) 
  row=(a(i,:)); 
  b=sort(row) 
end
I need an answer which is (b= 4×4 array) like the original (a)
cheers.

Are you trying to do:
a = [2 1 3 1
     1 4 1 5
     6 7 1 1
     8 1 9 1];
sort(a,2)
ans =
     1     1     2     3
     1     1     4     5
     1     1     6     7
     1     1     8     9
