Hi David,

> (2) Just iterating with "for" over all N cell entries and doing a fwrite per entry lacks efficiency.

Maybe you have implemented this efficiently, maybe you haven't. For a discussion about efficient code posting the original code is obligatory.

A = {[1,3;2,4] [] [5 6 7] [8;9;10]};
fid = fopen(FileName, 'w');
if fid == -1, error('Cannot open file for writing.'); end
for iC = 1:numel(C)
fwrite(fid, C{iC});
end

This is too slow?

Kind regards, Jan
