matlab怎么将字符数组输出到txt文本里？

如这样一个数组：

positionatom1 =
[ '                 0                   0  14.138181183815000 La';
  '                 0                   0   3.410323816185000 O ';
  ' 2.014519000000000   2.014519000000000  11.667720198420000 Cl';
  ' 2.014519000000000   2.014519000000000   5.880784801580000 As';
  ' 4.029038000000000                   0  14.138181183815000 Fe'];

你好，用fprintf和%s就行

positionatom1 =[ '                 0                   0  14.138181183815000 La';
    '                 0                   0   3.410323816185000 O ';
    ' 2.014519000000000   2.014519000000000  11.667720198420000 Cl';
    ' 2.014519000000000   2.014519000000000   5.880784801580000 As';
    ' 4.029038000000000                   0  14.138181183815000 Fe'];
fid = fopen('positionatom1.txt','wt');
for i =1:size(positionatom1,1)
    fprintf(fid, '%s\n',positionatom1(i,:));
end
