Storing concatenated string array problem

I have two 1xn matrices that I want to merge together. If array one held [1 PF Pop, 2 PF Pop, 3 PF Pop...] and the other contained [1 AF Pop, 2 AF Pop, 3 AF Pop], then I would like the result to be the concatenation and array of both elements.
% The desired result is shown below, a single matrix concatenated with both elements
|1 AF Pop 1 PF Pop, 1 AF Pop 2 PF Pop,...|
|2 AF Pop 1 PF Pop, 2 AF Pop 2 PF Pop,...|
|3 AF Pop 1 PF Pop, 3 AF Pop 2 PF Pop,...|
% my code so far is below
for P=1:3
F=P*3;
for G = 1:4
G=(G+1)*F;
divbytwo=G/2;
bact8(P,G)=divbytwo; %array of P+1 elements
end
end
bacttry=bact8;
bacttry(1,:)=[];
no_of_rows=size(bacttry);
no_of_columns=no_of_rows;
no_of_columns(:,1)=[];
no_of_rows(:,2)=[];
array_columns=strcat(strtrim(cellstr(num2str((1:no_of_columns)'))'),' PF Pop');
array_rows=strcat(strtrim(cellstr(num2str((1:no_of_rows)'))'),' AF Pop');

I have no idea which arrays you want to concatenate and into what. However you can create your two array_* much more simply with:
array_columns = compose('%d PF Pop', 1:no_of_columns);
array_rows = compose('%d AF Pop', 1:no_of_rows);
And your way of getting the number of rows and columns is extremely convoluted.
[no_of_rows, no_of_columns] = size(bacttry); %assuming that bacttry is 2D

Hello Matt,
You should consider using cell arrays for this purpose. To concatenate 2 1xn arrays to a single nxn matrix the code will be :-
x1= {'1 PF Pop', '2 PF Pop', '3 PF Pop'}
x2= {'1 AF Pop', '2 AF Pop', '3 AF Pop'}
x={}
for i=1:numel(x1)
for j=1:numel(x2)
x{i,j}=strcat(x1{i},x2{j});
end
end
Regards,
Krishna Madala
