You don't say how you want x printed but you don't need num2str at all. In fact, if you just want a table of the ending array x, probably using dlmwrite is the simpler solution.

dlmwrite('output.txt', x, 'delimiter', ' ', 'precision','%10.5f')

Salt to suit on format, delimiter, etc., ... see

doc dlmwrite  % for details

W/ low-level fprintf it'd be sotoo

fid=fopen('output.txt','w');
fprintf(fid,[repmat('%10.5f ',1,size(x,2)) '\n'], x.');
fid=fclose(fid)

NB: the .' transpose operation to get in row-major order and the explicit formatting.
