Combining 2 vectors?

Sorry if bit of a silly question but how would i combine 2 vectors as below? Thanks in advance

a1 [ 1,2,3,4,5,6] a2 [ 7,8,9,10,11]

a3 = [1,2,3,4,5,6,7,8,9,10,11]

Answer 1

[John D'Errico]

You created a1 as

a1 = [1,2,3,4,5,6];

and a2 as

a2 = [7,8,9,10,11];

So why would you not be able to create a3 as

a3 = [a1,a2];

TRY IT!

Thanks! My mistake why it didn't work when i tried it before!!

1. Input into MATLAB workspace the following vectors: A = (2 4 6 8), B = (5 10 15 20), and build up the vector C = (2 5 4 10 6 15 8 20).

[Chumani]

1. Define a vector Y = (4, 7, -5, 10, 11, 0, -3, 12, 8, 19) and compute:

• length(Y),
• size(Y),
• Y(10)=-Y(4),
• Y(11)=Y(7)-Y(3).

Make the third and fifth elements equal to nine

[Chaman Sabharawal]

x=1:2:16, y=12:2:16,

z(1:2:16) =x;

z(2:2:16)=y

merges x and y interveavingly

As the question was already answered but if you have a column vector like a1 = [1,2,3,4,5,6]';

a2 = [7,8,9,10,11,12]';

then you can use

a3 = [a1;a2]
