% 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';

别人帮我写的 matlab程序,我在command window 中直接复制后运行,出现下面的错误
但是别人说这个程序是正确的 ,希望大家指点下,是否要在 matlab中做何种设置呢 ?
