[Discuss-gnuradio] saving a complex data into a file

[Jose Torres Diaz]

Hi Community, 

I'm trying to save complex data from a block into a file, in order to process the information later on. My code is very simple, as shown bellow:

//Definition of values
std::vector<float> complex_values(4);
         
complex_values[0]=(-0.707,-0.707);  
complex_values[1]=(0.707,-0.707);  
complex_values[2]=(-0.707,0.707);  
omplex_values[3]=(0.707,0.707);  

myfile.open ("/home/usrpvm/Desktop/examples/binary_complex");

myfile <<(char*)&complex_values[0];
myfile <<(char*)&complex_values[1];
myfile <<(char*)&complex_values[2];
myfile <<(char*)&complex_values[3];

When I finish, I check my values with hexdump command:

hexdump binary_complex -v -e ' 2/4 "%10f "' -e '"\n"'
 -0.707000  -0.707000
  0.707000   0.707000
 -0.707000   0.707000
  0.707000   0.707000
  0.707000   0.707000

As you can see, there are more values that I'm saving and there are some values missing. I think I am doing something wrong when I save the values.

Anyone can point me to the right direction?

Thanks for your time, 

Jose.
