Add header to data file

Hello,

In my code below, I wanted to know how to go about adding a header to the file. The header will be the column names:

A B C D E. Thanks for your time and help. Here is my code:

A = 1:15;
B = (0.5)*rand(15,1);
C = 1:20;;
D = (0.5)*rand(20,1);
E = (0.5)*rand(20,1);

CELL{1} = A';
CELL{2} = B;
CELL{3} = C';
CELL{4} = D;
CELL{5} = E;

Astr = cell(20,5);

Astr = cellstr(num2str(A.', '%6.0f'));
Output(1:length(Astr), 1) = Astr;
Astr = cellstr(num2str(B, '%6.5f'));
Output(1:length(Astr), 2) = Astr;
Astr = cellstr(num2str(C.', '%6.0f'));
Output(1:length(Astr), 3) = Astr;
Astr = cellstr(num2str(D, '%6.5f'));
Output(1:length(Astr), 4) = Astr;
Astr = cellstr(num2str(E, '%6.5f'));
Output(1:length(Astr), 5) = Astr;

fileID = fopen('check.dat','wt');
fmt = '%s,%s,%s,%s,%s\n';
OutTranspose = Output .';   %need to transpose it
fprintf(fileID, fmt, OutTranspose{:});
fclose(fileID);
