writing a matrix into a .txt file

I have a matrix of 65x10 and i want to open and write 9 txt files (from 2:10) each named by the first row at its column and contains two columns: the first column is the first column of the matrix (contains str) and the second one is the i'th column of the matrix (contains int) (starting from the second row). Also I need a title for both columns in each file.
Thanks, Oded

You do not specify what kind of matrix you have, so I will assume that it is a cell array (as a numeric array would not hold string/char data). This code should get you started, please experiment and adapt as required:
P = '.'; % directory path
C = 65x10 cell array
for k = 2:size(C,2)
N = sprintf('column_%d.csv',k);
[fid,msg] = fopen(fullfile(P,N),'wt');
assert(fid>=3,msg)
fprintf(fid,'%s,%s\n',C{1,[1,k]});
tmp = C(2:end,[1,k]).';
fprintf(fid,'%s,%d\n',tmp{:});
fclose(fid);
end
