function data=sin_mif_data_generation

%使用MATLAB生成正弦波的MIF文件

%2010.2.10

%生成数据

N=8;

index = linspace(pi,3*pi,2^N);

sin_value = sin(index);

sin_value = sin_value * 220*2^7;

sin_value =round(sin_value);

%  plot(sin_value) %画图看波形用

%控制格式输出

number=[0:2^N-1];

for i=1:2^N

colon(i)=':';

end

colon

for i=1:2^N

semicolon(i)=';';

end

data=[number; colon; sin_value; semicolon];

fid=fopen('E:\ualfa_mif_data.txt','w');

fprintf(fid, '%d%c%d%c\n', data);

fclose(fid);

生成的文件是下面的，请问问题在哪？
