I want to make a 3*12 matrix which its first, second and third row is N1, N2 and N3.
N1, N2 and N3 are 1*12 vectors.
I can use [N1(1) N1(2) ....N1(12); N2(1) N2(2) ....N2(12); N3(1) N3(2) ... N3(12)]
but it's ugly and slow, I want to use Matlab special features in matrix handling.

N = [N1; N2; N3];

You have a general function of concatenation that you could look at. Learn to handle it, it is very useful !
>> help cat
It should solve your problem with
>> cat(1,N1,N2,N3)
Note : it is equivalent to
>> [N1;N2;N3]
