This is a binary file, so you would need to use low-level functions such as fopen, fread, and fclose to get the data into MATLAB.
Even though FREAD will read in numeric data, it is important to understand how the data is encoded, or else the data you read in may not make sense.
You can learn more about file I/O at this link:
