Intel hex 文件常用来保存单片机或其他处理器的目标程序代码。它保存物理程序存储区中的目标代码映象。一般的编程器都支持这种格式。
Intel hex 文件全部由可打印的ASCII字符组成（可以用记事本打开），如下例所示：
:2000000012014c75a800e4f508f509780a7a78e4f608dafcd283fcfded240af9a7050dbd81
:2000200000010ced2488ec34ff50edc283e4fcfded240af9e76d7013ed33e43c700d0dbd2a
:2000400000010ced2488ec34ff50e50509e50970020508e50924a8e50834fd50aee4f50874
Intel hex 由一条或多条记录组成，每条记录都由一个冒号“:”打头，其格式如下：
:CCAAAARR...ZZ
其中:
CC
本条记录中的数据字节数
AAAA
本条记录中的数据在存储区中的起始地址
RR
记录类型：
00 数据记录 (data record)
01 结束记录 (end record)
02 段记录 (paragraph record)
03 转移地址记录 (transfer address record)
...
数据域
ZZ
数据域校验和
Intel hex文件记录中的数字都是16进制格式，两个16进制数字代表一个字节。CC域是数据域中的实际字节数，地址、记录类型和校验和域没有计算在内。校验和是取记录中从数据字节计数域(CC)到数据域(...)最后一个字节的所有字节总和的2的补码。

% 用matlab产生hex文件
function hexfile(filename,var,databytenum,firstaddr,record_set,depth)
% function hexfile(filename,var,width,depth)
% It creates a 'hex' file called filename,which be written with var.
% The 'mif' file is a kind of file formats which is uesed in Altera's
% EDA tool,like maxplus II ,quartus II,to initialize the memory
% models,just like cam,rom,ram.
% Using this function,you can easily produce the 'hex' file written
% with all kinds of your data.
% If the size of 'var' is shorter than 'depth',0 will be written for the
% lefts.If the size of 'var' is greater than 'depth',than only 'depth' former
% data of 'var' will be written;
% the radix of address and data is hex
% filename --the name of the file to be created,eg,"a.hex",string;
% var --the data to be writed to the file, can be 3D or less ,int or other fittable;
% databytenum --the num of byte in the every record,int,dec;
% firstaddr --the first address of the data to be stored in the memory,int,dec;
% record_set --the record style of the data,int,dec;
% depth --the number of the record to be writed,int;
% because matlab read the matrix is colum first,if you want to write
% the 'var' data in row first mode, just set var to var';
