now I need to read data from this .txt.. my code is
fid = fopen('D:\data_1.txt');
A = fscanf(fid, '%g', [2 inf]);
fclose(fid);
X=reshape(A,20000,1);
but I am getting error on RESHAPE function...it says "To RESHAPE the number of elements must not change."
in workspace A is blank..whats going wrong?

Hi,
Can you try to use the default setting of FSCANF function?
Like A=fscanf(fid,'%g');
