n = [1 2 3 4 5]

n =

1 2 3 4 5

>> r = n'

r =

1

2

3

4

5

Then i want to change into row vector again??

To convert a column vector back into a row vector, use the transpose operation. Simply apply the transpose operator (') to the column vector to obtain the row vector.

Simply converting a row vector into a column vector needs the usual transpose operator which is .' You used only ' with is conjugate transpose. This will make a difference if the elements of the vector are complex numbers:

n = [1+1i,2-0.5*1i];
n'
ans = 
   1.0000 - 1.0000i
   2.0000 + 0.5000i
n.'
ans = 
   1.0000 + 1.0000i
   2.0000 - 0.5000i

To change the column vector into the original row vector, use .' again:

n = [1 2 3 4 5];
n.'
ans = 5x1
     1
     2
     3
     4
     5

ans = 1x5
