concatenate each element of two arrays

I have two arrays, can you please help me how can I concatenate each element of both arrays.

e.g. A=['a' 'b' 'c'] B = ['1' '2']

I want ['a1' 'a2' 'b1' 'b2' 'c1' 'c2']

Thanks

you can do it using for loop

Answer 1

[Azzi Abdelmalek]

A=['a' 'b' 'c'];
B = ['1' '2'];
[ii,jj]=ndgrid(1:numel(A),1:numel(B));
out=arrayfun(@(x,y) [A(y) B(x)],jj(:),ii(:),'un',0);
out=sort(out)

+1 that's neat Azzi

Thanks Azzi!

No need for arrayfun to concatenate, or using sort when you re-arrange the inputs and outputs to/from ndgrid:

[bb,aa] = ndgrid(B,A) ; 
C = [aa(:) bb(:)]

Answer 2

[Jan]

A = {'a' 'b' 'c'};
B = {'1' '2'};
C = strcat(repmat(A, 2, 1), repmat(B', 1, 3))

Notice that A and B are cell strings, not char vectors.

Mohit, this also gives you what you want, just add

C(:)'

Answer 3

[Jos (10584)]

A=['a' 'b' 'c']
B = ['1' '2']
C = allcomb(A,B)

ALLCOMB can be found here: http://www.mathworks.com/matlabcentral/fileexchange/10064-allcomb

Answer 4

[Wayne King]

Make A and B cell arrays of strings, but B has to be the same length as A so you'll have to repeat the 2

 A = {'a','b','c'};
 B = {'1','2','2'};
 strcat(A,B)

Thanks, it will give me 3 elements in result matrix while I wanted 6.
