Here is my code
clc
clear
beam = {'A';'B';'C';'D';'E';'F';'G';'H';'I';'J';'K';'L';'M';'N';'O';'P';'Q'}
column = {'A';'B';'C';'D';'E';'F';'G';'H';'I';'J';'K';'L';'M';'N';'O';'P';'Q'}
for i = 1 : length(beam)
x(i) = string(beam(i))
for j = 1 : length(column)
y(j) = string(column(j))
xy(i) = append(x(i),y(j))
end

Your code can be optimized, but here are the minimal changes.
beam = {'A';'B';'C';'D';'E';'F';'G';'H';'I';'J';'K';'L';'M';'N';'O';'P';'Q'};
column = {'A';'B';'C';'D';'E';'F';'G';'H';'I';'J';'K';'L';'M';'N';'O';'P';'Q'};
xy=repmat("",numel(beam)*numel(column),1);
k=0;
for i = 1 : numel(beam)
x = string(beam(i));
for j = 1 : numel(column)
y = string(column(j));
k=k+1;
xy(k) = x+y;
end
end
xy
xy = 289×1 string array
"AA" "AB" "AC" "AD" "AE" "AF" "AG" "AH" "AI" "AJ" "AK" "AL" "AM" "AN" "AO" "AP" "AQ" "BA" "BB" "BC" "BD" "BE" "BF" "BG" "BH" "BI" "BJ" "BK" "BL" "BM"
Now for the more compact version (using implicit expansion and transposing with .'):
beam = {'A';'B';'C';'D';'E';'F';'G';'H';'I';'J';'K';'L';'M';'N';'O';'P';'Q'};
column = {'A';'B';'C';'D';'E';'F';'G';'H';'I';'J';'K';'L';'M';'N';'O';'P';'Q'};
xy = string(beam).'+string(column);
xy = xy(:);
xy
xy = 289×1 string array
"AA" "AB" "AC" "AD" "AE" "AF" "AG" "AH" "AI" "AJ" "AK" "AL" "AM" "AN" "AO" "AP" "AQ" "BA" "BB" "BC" "BD" "BE" "BF" "BG" "BH" "BI" "BJ" "BK" "BL" "BM"
Or perhaps even this:
beam = string(num2cell('A':'Q'));
column = string(num2cell('A':'Q'));
xy = reshape(beam+column.',[],1);
xy
xy = 289×1 string array
"AA" "AB" "AC" "AD" "AE" "AF" "AG" "AH" "AI" "AJ" "AK" "AL" "AM" "AN" "AO" "AP" "AQ" "BA" "BB" "BC" "BD" "BE" "BF" "BG" "BH" "BI" "BJ" "BK" "BL" "BM"
