Open .bin file contains words and floating numbers

Hi people,

I have some .bin file and trying to open it but what I got is not what it should be. The file contains words and floating numbers. Please see attached two files: one .bin file and one .txt file. I just check in .txt file what should be in file after I open the same .bin file in matlab.

Thank you.

I try:

datar=fopen(FD_file_path,'r');
x = fread(datar,'int16');
x = fread(datar, inf, 'float32');

Without knowing the format of the file, it's going to be effectively impossible to interpret the data you read from the file.

Which of the 12 programs on this list created your .bin file? Or was it created by some other program in its own format?

If you don't know the format of the file, your .txt file may be able to serve as a Rosetta Stone to help you reverse engineer the format.

You probably want to use *int16 and *float32 as the precision inputs to fread so fread reads them in as int16 or single data and returns them as int16 and single arrays respectively, rather than returning them as double arrays.

Depending on the endianness of the data you may need to use swapbytes as well.
