整数编码 [英] Integer encoding

问题描述

我试图找出如何根据给定的参数对整数进行编码。例如，我给了表：

  integer = 0，编码为3294 
 
 integer = 1，编码为128 
 
整数= 2，编码为2098 
  

等。

我该怎么做？我看过函数dec2bin，但这不是我需要的。我的输入将是一个向量，例如 x = [2 1 0] ，输出将为向量 y = [2 0 9 8 1 2 8 3 2 9 4] 。

任何建议或帮助都是赞赏！

解决方案

编码可能不成为描述这个的最好的话。这个答案只是搜索中的一个方向。

我会看看任何字典， hashtable 或 map 数据结构。以下代码基于此帖中描述的解决方案

  c = containers.Map; 
 c（'0'）= 3294; 
 c（'1'）= 128; 
 c（'2'）= 2098; 
键（c）
值（c）
  

您可能需要添加正确使用，也可以直接使用整数类型来删除转换和转换开销。

I am trying to figure out how to encode integers based on given parameters. For example, I am given the table:

integer = 0, encoding is 3294 

integer = 1, encoding is 128 

integer = 2, encoding is 2098

etc.

How would I go about doing this? I have looked at the function dec2bin, but it's not exactly what I need. My input would be a vector, say x = [ 2 1 0 ] and the output would be the vector y = [2 0 9 8 1 2 8 3 2 9 4].

Any advice or help is appreciated!

解决方案

Encoding may not be the best word to describe this. This answer is just a direction in your search.

I would have a look at any dictionary, hashtable or map data structures. Code below is based on solution described in this post

c = containers.Map;
c('0') = 3294; 
c('1') = 128;
c('2') = 2098;
keys(c) 
values(c)

You may need to add proper usings and maybe use integers types directly to remove casts and conversion overhead.
