Structure Export

I am trying to do something which I feel is pretty simple. I'm trying to export each of 4 fields from a structure to a .txt file. I'd like the text file to be comma delimited. 3 of my fields are character and 1 is double. Is this a fairly simple thing to do?

Thanks, Brian

Structure, or structure array?

Structure case:

t = struct2cell(S);
fprintf(fid, '%s,%s,%s,%f\n', t{:});

I'm still pretty new to Matlab so I'm not sure how to tell if it's simply a structure or a structure array. The struct2cell command worked just fine, creating a 4x1x4158 cell. However, I was having trouble with the second command. To obtain a file ID I tried the fopen command, but it doesn't seem to want to create a new file, just open one that already exists.

fid = fopen('OutputFile.txt','wt')
