MATLAB学习(十)实现文件、图像读写

 

t=1:5;
s1=sin(t);
s2=cos(t);
s=[t;s1;s2];
fid1=fopen('test.dat','wt');
fprintf(fid1,'
This is a Formated file
');
fprintf(fid1,'
%4d   %+12.5E  %+12.5E
',s);
fclose(fid1);
fid2=fopen('test.dat','rt');
[A1,count1]=fscanf(fid2,'%s',5);
[A2,count2]=fscanf(fid2,'%4d  %e  %e',[3,inf]);
A2=A2';
fclose(fid2);

  

fid=fopen('d:data.txt','r')
line=fgetl(fid)
k=findstr(line,'cgg')
s=length(k)
line=fgetl(fid)
k=findstr(line,'cgg')
s=length(k)
fclose(fid)
-------
for k=0:99
p=int2str(k);
fname=strcat('picture',p,'.bmp') %构成一有规律的文件名
打开图像fname
进行处理;
关闭当前图像文件;
end
