function data=sin_mif_data_generation
%使用MATLAB生成正弦波的MIF文件
%.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？
