我将此代码放在名为createTeamDict.m的文件中:
function [ team_dict ] = createTeamDict( team_names, team_ids )
%createTeamDict takes in a cell array of team names and a vector of
%corresponding team IDs and returns an appropriate dictionary, mapping team
%names to their IDs
team_dict = containers.Map;
for i = 1 : length(team_names)
team_dict(team_names{i}) = team_ids(i);
end
end
然后在我正在运行的文件中,我有:
team_names = {'Trinity', 'SLU', 'Harvard', 'Columbia', 'Rochester', 'Yale', 'Upenn'};
team_ids = [11324 11351 11314 11326 11316 11315 11317];
team_dict = createTeamDict(team_names, team_ids);
出于某种原因,我在尝试运行时遇到此错误:
“使用createTeamDict时出错(第6行) 没有足够的输入参数。“
为什么会出现这种情况?
谢谢,

根据我们的评论,该文件未被保存。只需保存文件即可。
为了提高效率,您无需循环遍历每个键/值对,以此方式创建containers.Map
。您可以使用一组输入键/值对初始化字典:
team_dict = containers.Map(team_names, num2cell(team_ids));
我们得到:
>> team_dict
team_dict =
Map with properties:
Count: 7
KeyType: char
ValueType: double
