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 apply the transpose operator (')..."
' is the operator for complex conjugate transpose: https://www.mathworks.com/help/matlab/ref/ctranspose.html

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
