How do I format and write a numeric array to a file as text?

What's the easies way to write an array to a formatted file. If I have 16 columns, it seems cumbersome that I have to specify the individual format for each column and then print it in a for loop. Isn't there something like this?
Arrayprint(fid,Data,'f10.5')
thanks

DLMWRITE can create such files. But FPRINTF is vectorized also, so you do not need a loop:
x = rand(100, 16);
fmt = [repmat('%10.5f ', 1, 15), '%10.5f\n'];
fid = fopen(FileName, 'w');
fprintf(fid, fmt, x'); % transposed!
fclose(fid);
