How do I read in specific parts of a binary file?

Hi all,
I would like to simply read in a specific, pre-determined length of a binary file in MATLAB. The file is huge, and I cannot/don't want to simply read all of it at once.
I have looked at the 'skip' command within fread but I do not want to skip chunks, I just have one chunk that I want to read in, and be done with it.
How can this be done? (The file is an int16 .bin file).
For example: My file has 1e6 samples, and it int16. I want to ONLY read in the values from sample, say, 433,232, up to, 546,323. How can this be done?
Thanks

Use fseek and then fread.

fseek(fid, OFFSET, 'bof')
OFFSET would start at 0 for the first byte of the file.
