Saved data from Matlab gets corrupted?

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?

The reason why it's wrong is explained by Walter Roberson.

What you can do to probably get your intended result is to use

fprintf

instead of

fwrite

Then you can write your data to the file in text format instead of binary format.
