It sounds like, as Dan suggested, you want to display the transpose of your vector, i.e. a row vector rather than a column vector:
>> A = rand(1,20)
A =
Columns 1 through 7:
0.681499 0.093300 0.490087 0.666367 0.212268 0.456260 0.532721
Columns 8 through 14:
0.850320 0.117698 0.567046 0.405096 0.333689 0.179495 0.942469
Columns 15 through 20:
0.431966 0.100049 0.650319 0.459100 0.613030 0.779297
>> A'
