All variables are stored as double precision floats in matlab by default.
there is no unsigned int representation in Matlab (unless the latest and
greatest release has some new data type).

so if you did
x = 2843;
it will be stored as 2843.00 and x will be a floating point number. There is
no specific syntax you need to do this.

hi,
it seems that 12-bits are not supported in these format.  however even if
i convert these to 16-bits, there is still no result of the conversion!
Does anyone have an idea about this conversion! What could be the
appropriate syntax?
thanks again!

have you tried looking at the help for fread?  using bit12 or ubit12 as a 
format?

Hello

Does anyone have a hint on how to convert a set of 12-bites unsigned
interger to float, using matlab?
Matlab shows the following syntax using float

a = float('single')
a = float('double')
a = float(TotalBits, ExpBits)

// here is an example of 12-bit unsigned int
x=[
2843
2845
2851
2869
2838
2840
2853
2864];

I have tried these 3 float syntaxes , but i don't get any conversion?
Any ideas on how to use them??
Thanks in advance!
