Hello to everyone,

I have a code in ".mfile" which generates a 1X14240 data. The output data is composed of complex numbers, which all appear well at the command line. However, whenever I write the data into either a ".dat", or ".txt" file, I find it all corrupted by the time I open it up. What could be possibly wrong with it? Could it be that the data length is too long?.

Here is the code I used for saving the file:

filename='filename.txt';
fid = fopen(filename,'w');
newshape = reshape([real(data);imag(data)],1,2*length(data));
F = fwrite(fid,newshape,'float');
fclose all;

Thanks for your anticipated responses

To check: you do know that fwrite() is to write binary data? So even though you named your file with .txt, the file will not have the numbers in readable form?
