Matlab: concat row vectors into an array

问题:

how can I add, for example vector

v1 = [0 0 0 1]
v2 = [0 1 0 0]

so that I get an array

a = 0 0 0 1
    0 1 0 0

and also add more vectors to, into array a?

回答1:

if you have 2 row vectors v1 = [0 0 0 1], and v2 = [0 1 0 0]

v3 = [v1, v2] yields

v3 = [ 0 0 0 1 0 1 0 0 ]

v3 = [v1; v2] yields

v3 =
[ 0 0 0 1
0 1 0 0 ]

回答2:

A part from the prior answers I suggest that you check the following functions: horzcat, vertcat and reshape.

For instance test this code:

A1 = [1 2 3; 4 5 6; 7 8 9];
A2 = A1 + 10*ones(3,3); 
B1 = horzcat(A1,A2)         % horizontal concatenation
B1 = vertcat(A1,A2)         % vertical concatenation
v1 = reshape(A, 1, prod(size(A)))   % easily change the size of matrix

Just concatenate them by using the following syntax:

a = [v1 v2]

Hope this works
