.mat file to bin file

Hi, I have recorded some WCDMA data using gnuradio and USRP which is in .bin format with 32bit floating point (both I and Q). I used octave to read that bin file and converted to .mat file so that it be imported into MATLAB. I did some signal processing on that data. Now I want that .mat file to be converted back to .bin file. I searched but couldn't succeed. Any pointers ?

".bin" as a file extension is not at all standardized. It can be used for any binary file format. We cannot advise on how to create .bin files without documentation on the exact file format.

Probably something like

filename = 'OUTPUTFILENAMEGOESHERE.bin';
[fid, msg] = fopen(filename, 'w');
if fid < 0; error('Failed to open "%" because "%s"', filename, msg); end

IQ = single([reshape(I, 1, []), reshape(Q, 1, [])]);
fwrite(fid, IQ, 'float32');

fclose(fid);

Hi Sumit,

To convert .mat file to bin file, dec2bin function can be used. Please refer to the following MATLAB Answers post which discusses about the same process:

dec2bin is absolutely completely unrelated to the task of building .bin files.
