编写错误怎么改正确啊

function [num,strs ] = strnum(s)
n=length(s);
ls=('a'<=s & s<='z') | ('A'<=s & s<='Z');
flag=1;
num=0;

for i=1:n

if ls(i)==1 && flag==1
    num=num+1;
    strs(num).word=s(i);
     strs(num).len=1;
    flag=0;
elseif ls(i)==1 && flag==0
     strs(num).word=[ strs(num).word,s(i)];
     strs(num).len= strs(num).len+1;
elseif ls(i)==0 && flag==0
     
    flag=1;
end

end

end

求求了
