问题描述
我试图将中的一些matlab代码转换成可以工作的东西与八度。我目前陷入困境，因为其中一个文件对 containers.Map 有几个调用，这显然是。有没有人有任何想法轻松实现类似的功能，而不需要在八度音阶上做很多额外的工作？感谢您的时间。

解决方案
在Octave中并没有完全等价的
在Octave中并没有完全等价的
containers.Map 一种选择是使用创建 java。 util.Hashtable 。使用此：
pkg load java
d = javaObject（java.util.Hashtable）;
d.put（'a'，1）
d.put（'b'，2）
d.put（'c'，3）
d.get 'b'）
如果您愿意有一点重写，你可以使用内建的 struct 作为一个基本的散列表，字符串（有效变量名）作为关键字，以及存储在值中的任何东西。
例如，给定以下内容：
keys = {'Mon'， 'Tue'，'Wed'}
values = {10,20,30}
你可以替换它：
map = containers.Map（keys，values）;
map（'Mon'）
by：
s = struct（）;
for i = 1：numel（keys）
s。（keys {i}）= values {i};
end
。（'Mon'）
您可能需要使用 genvarname 来产生有效的密钥，或者是一个合适的哈希函数来产生有效的密钥字符串。
相关函数：getfield，setfield，isfield，fieldnames，rmfield等。
I am trying to convert some matlab code from the Maia package into something that will work with Octave. I am currently getting stuck because one of the files has several calls to containers.Map which is apparently something that has not yet been implemented in octave. Does anyone have any ideas for easily achieving similar functionality without doing a whole lot of extra work in octave? Thanks all for your time.

解决方案
There is no exact equivalent of containers.Map in Octave that I know of...
One option is to use the java package to create java.util.Hashtable. Using this example:
pkg load java
d = javaObject("java.util.Hashtable");
d.put('a',1)
d.put('b',2)
d.put('c',3)
d.get('b')
If you are willing to do a bit of rewriting, you can use the builtin struct as a rudimentary hash table with strings (valid variable names) as keys, and pretty much anything stored in values.
For example, given the following:
keys = {'Mon','Tue','Wed'}
values = {10, 20, 30}
you could replace this:
map = containers.Map(keys,values);
map('Mon')
by:
s = struct();
for i=1:numel(keys)
s.(keys{i}) = values{i};
end
s.('Mon')
You might need to use genvarname to produce valid keys, or maybe a proper hashing function that produces valid key strings.
Also look into struct-related functions: getfield, setfield, isfield, fieldnames, rmfield, etc..
