最近调试串口发现matlab突然不会用了，于是决定记录一下解决方法

fidin=fopen('file1.txt');%比较复杂的，每行的列数不一致的，特殊字符
a=textscan(fidin,'%s');
f(:,1)=a{1}(14:17:end,1);f(:,2)=a{1}(15:17:end,1);
fclose(fidin);

g=cellstr(cell2mat(f));%合并两列
alpha=hex2dec(g);
fidout=fopen('dian.txt','w');
fidout2=fopen('dianya.csv','w');

for i=1:length(alpha)
fprintf(fidout,'%.4f\r\n',alpha(i)*0.01); 
fprintf(fidout2,'%.4f\r\n',alpha(i)*0.01);%按列输出，若要按行输出：fprintf(fid,'%.4\t',A(jj)); 
end
fclose(fidout);

[x y]=size(alpha);
b=(1:1:x)/10;
xlswrite('out.xlsx',b','Sheet1','A1');
xlswrite('out.xlsx',alpha*0.01,'Sheet1','B1');
% d=a{1}(14:17:end,1);
% e=a{1}(15:17:end,1);
% fprintf(fidout,'%s\n\n',alpha);
