I am trying to create a string array of elements ranging from A1 to H12, where the first 12 elements are A1 - H1, next 12 are A2 - H2 and so on. I want to do this without having to type these out in a comma separated list. Here is my failed attempt at programming this.
Rows = {'A','B','C','D','E','F','G','H'};
Cols = [1:1:12];
wellNames = NaN(1,96);
count = 1;
for y = Cols
ystr = sprintf('%d', y);
for x = Rows
tempstr = num2str(cell2mat([x, ystr]));
wellNames(:,count) = tempstr;
count = count + 1;
end
end

Like this?
c = 'A':'E'
c = 'ABCDE'
s = string(c')
s = 5×1 string array
"A" "B" "C" "D" "E"
M = s + (1:6)
M = 5×6 string array
"A1" "A2" "A3" "A4" "A5" "A6" "B1" "B2" "B3" "B4" "B5" "B6" "C1" "C2" "C3" "C4" "C5" "C6" "D1" "D2" "D3" "D4" "D5" "D6" "E1" "E2" "E3" "E4" "E5" "E6"

To change the shape of an array you can use reshape.
c = 'A':'E';
s = string(c');
M = s + (1:6);
rv = reshape(M, 1, [])
rv = 1×30 string array
"A1" "B1" "C1" "D1" "E1" "A2" "B2" "C2" "D2" "E2" "A3" "B3" "C3" "D3" "E3" "A4" "B4" "C4" "D4" "E4" "A5" "B5" "C5" "D5" "E5" "A6" "B6" "C6" "D6" "E6"
cv = reshape(M, [], 1)
cv = 30×1 string array
"A1" "B1" "C1" "D1" "E1" "A2" "B2" "C2" "D2" "E2" "A3" "B3" "C3" "D3" "E3" "A4" "B4" "C4" "D4" "E4" "A5" "B5" "C5" "D5" "E5" "A6" "B6" "C6" "D6" "E6"
