code shows error in function

Asked by Lalit Patil on 21 Dec 2012

I am using following code to write text file.. This is the part of a function.. and it works...

 fid = fopen(sprintf('Image%d.txt',imageNumber),'wt');
 for j=1:length(y),
    fprintf(fid,'%f %f\n',y(j),x(j));

Now when i am using following code to read the same file then it shows error..


 C = textscan('Image%d.txt',imageNumber);

You do not textscan() a file name: you textscan() a file identifier created by fopen()

fid = fopen(sprintf('Image%d.txt',imageNumber),'rt');
C = textscan(fid, '%f%f');
