[EDIT: 20110612 11:45 CDT - reformat - WDR]

Hello, i am recently have to read out a binary file. The whole information about this file is as:

Description: Raw Accelerometer Vector
Notes: This vector represents the raw binary values of the accelerometers before normalization, scaling and temperature compensation.
Field Format 
Field Length 
Data Descriptor  0x01  
Message Data  
Binary Offset Description      Data Type      Units
0              Accel 1          float          bits
4              Accel 2           float          bits
8              Accel 3           float          bits

What is your Matlab related question? What did you try so far and which problems occurred?

What is the length of the Field Format? Of the Field Length? Is the data descriptor a single byte? Is Message Data a field distinct from the accelerations?

I do not know of any floating point format that can fit in 4 bits. 4 _byte_ floating points are not uncommon, but the description does specifically say bits.

You do not present sufficient information for us to deduce how long the third acceleration is.

If you do have any multi-byte data, we need to know the byte order.

We need to know the floating point format.
