I tried this:
fid=fopen("somefile.txt","w")
for index=1:size(cell,1)
fprintf(fid,"%i %i = %i\n",cell(index,1),cell(index,2),cell(index,3));
end
fclose(fid);
but first, I have to convert the matrix that was in the cell, to a matrix (cell2matrix). But the output to the file was bad. it print a matrix, in a line...
