Question

在代码中，“createbook”和“displaybook”是我创建的函数，我知道这些工作并不是问题。如果有人可以帮助我，我会非常感激。如果您需要更多信息，请发表评论然后回复您

Books = [];

Choice = input('What would you like to do: ','s'); 

while (Choice)

   if Choice == 'add book'

      Title = input('Enter the title: ','s');
      Author = input('Enter the author: ','s');
      Pages = input('Enter the number of pages: ');

      New = createbook(Title, Author, Pages);

      displaybook(New);

      fprintf('%s has been added to the library\n',New)

      Books = [Books New];

   elseif Choice == 'quit'

      disp('PROGRAM END')

      return;  

   end

   Choice = input('What would you like to do: ','s'); 

end

使用strcmp代替（==）。原因是当您在Matlab中写入if（＆＃39; string1＆＃39; ==＆＃39; string2＆＃39;）时，它返回一个布尔向量，它检查每个索引i是否为（str1 [i] ] == str2 [i]）。如果两个字符串具有不同的长度，则会抛出异常
