combine each entry of a cell array and a double array

I have two arrays - one cell array and one double array, can you please help me how can I combine each element of both arrays.

e.g. A is a cell array of 3 rows (with elements A1,A2,A3) and B is double array of 2 rows (with elements B1 and B2)

I want a 3*2 array like below array

 A1B1 A1B2
 A2B1 A2B2
 A3B1 A3B2

Thanks

So is A is a cell array of chars, and B is a standard array of doubles, and you want to combine it into a cell array of chars.

A = {'1928.T' '2503.T' '2914.T' '3382.T' '3407.T'}
B = [733263 733264 733267]

[Aix,Bix] = ndgrid(1:numel(A), 1:numel(B))
fh = @(k) sprintf('%s%d',A{Aix(k)},B(Bix(k)))
C = arrayfun(fh,1:numel(Aix),'un',0)
% and reshape, transpose accordingly ...

This is exactly what I was looking for. Thanks a lot Jos, You are a star!!!!

As you mentioned, I now just need to reshape.

A= {'A1' 'A2' 'A3'}
B= {'B1' 'B2' }

for ii= 1:length(A)
for jj=1:length(B)

out{ii,jj}=[A{1,ii} B{1,jj}];
end
end

 out

A={'A1','A2','A3'}
B={'B1','B2'}
[ii,jj]=ndgrid(1:numel(A),1:numel(B))
strcat(A(ii(:))',B(jj(:))')

%or

A={'A1','A2','A3'}
B={'B1','B2'}
n=numel(A);
m=numel(B);
[ii,jj]=ndgrid(1:n,1:m)
q=reshape(strcat(A(ii(:))',B(jj(:))'),n,m)
% You can add
out=arrayfun(@(x) [q{x,1} ' ' q{x,2}],(1:n)','un',0)

Array B is double array so it is giving me error.

[Mohit]

Even after converting B to cell array. I am unable to get the desired result. Not sure why this is happening as I dont see elements of double array in the final result. I am beginner in matlab and have gone nuts on this problem. Pls help!

'1928.T' '1928.T' '1928.T'

'2503.T' '2503.T' '2503.T'

'2914.T' '2914.T' '2914.T'

'3382.T' '3382.T' '3382.T'

'3407.T' '3407.T' '3407.T'

Answer 4

[Jos (10584)]

Your talking about doubles in B? What does A1B1 mean in that case? What is A1

% Assuming all doubles
A = {10 ; 11 ; 12}
B = [7 13]

Adouble = [A{:}] 
% some juggling with order, transposes and concatenations ... 
[bb,aa] = ndgrid(B,Adouble)
R = reshape([aa(:).' ; bb(:).'],numel(B)*2,[]).'

[Jos (10584)]

Note that

[aa,bb] = ndgrid(Adouble, B)
R = [aa(:) bb(:))

returns the same information ...

[Mohit]

Sorry for not being clear. So lets say A is a cell array with below components

1928.T

2503.T

2914.T

3382.T

3407.T

and B is a double array with below components:

733263

733264

733267

I want a matrix as below:

1928.T733263 2503.T733263 2914.T733263 3382.T733263 3407.T733263

1928.T733264 2503.T733264 2914.T733264 3382.T733264 3407.T733264

1928.T733267 2503.T733267 2914.T733267 3382.T733267 3407.T733267
