so as i understand binary vectors are a semi new thing to matlab?

I need to convery a binary vector to a signed int

I used to do this using the base2dec function and type cast it as a singed int

However, that is no longer feasible with a binary vector that is formed from using the hextobinaryvector function

So my question is, how can you create a signed int from a binary vector like the one returned from hextobinaryvector?

Thanks

I don't have the toolbox needed for hextobinaryvector(), but I assume the binary vector is just that. Given this solution:

One can extend it to accept binary values expressed as logical vectors instead of character vectors simply:

d = logical([1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]);
typecast(uint16(bin2dec(sprintf('%d',d))),'int16')
ans = int16
