Converting 16-bit, little-endian, 2's complement integer to regular integer

I'm trying to get various data sets (accelerometer, gyroscope etc.) from a AHRS (a CHR-UM6) and I'm having trouble getting the values out in the correct form. The data received (for each value) is a two row column vector such as:
247
255
These numbers are 16-bit, little-endian, 2's complement and I need to get the actual value. I hope someone can help!
Thanks, Ben

swapbytes(typecast(TheByteVector, 'int16'))
TheByteVector should be uint8.

gyro_x = double(typecast(uint8(packet.data([2 1]),'int16')) * 0.0610352;
No need to call swapbytes if you don't need to ;-)
