我正在尝试将一些matlab代码从Maia package转换为可与Octave一起使用的代码。我目前陷入困境，因为其中一个文件有多次调用containers.Map，这显然是not yet been implemented in octave的内容。有没有人有任何想法可以轻松实现类似的功能，而无需在八度音程中完成大量的额外工作？谢谢大家的时间。

我知道Octave中没有containers.Map的确切等价物......
一种选择是使用java package创建java.util.Hashtable。使用此example：
pkg load java
d = javaObject("java.util.Hashtable");
d.put('a',1)
d.put('b',2)
d.put('c',3)
d.get('b')
如果您愿意进行一些重写，可以使用内置struct作为基本哈希表，其中包含字符串（有效变量名称）作为键，以及存储在值中的任何内容。
例如，给出以下内容：
keys = {'Mon','Tue','Wed'}
values = {10, 20, 30}
你可以替换它：
map = containers.Map(keys,values);
map('Mon')
由：
s = struct();
for i=1:numel(keys)
s.(keys{i}) = values{i};
end
s.('Mon')
您可能需要使用genvarname来生成有效密钥，或者使用正确的散列函数来生成有效的密钥字符串。
另请参阅与结构相关的函数：getfield，setfield，isfield，fieldnames，rmfield等。
