% -*- texinfo -*- % @deftypefn {Function File} {} riceenco (@var{sig}, @var{K}) % % Returns the Rice encoded signal using @var{K} or optimal K . % Default optimal K is chosen between 0-7. Currently no other way % to increase the range except to specify explicitly. Also returns % @var{K} parameter used (in case it were to be chosen optimally) % and @var{Ltot} the total length of output code in bits. % This function uses a @var{K} if supplied or by default chooses % the optimal K for encoding signal vector into a rice coded vector. % A restrictions is that a signal set must strictly be non-negative. % The Rice algorithm is used to encode the data into unary coded % quotient part which is represented as a set of 1's separated from % the K-part (binary) using a zero. This scheme doesnt need any % kind of dictionaries and its close to O(N), but this implementation % *may be* sluggish, though correct. % % Reference: Solomon Golomb, Run length Encodings, 1966 IEEE Trans % Info' Theory % % An exmaple of the use of @code{riceenco} is % @example % @group % riceenco(1:4) % % riceenco(1:10,2) % % @end group % @end example % @end deftypefn % @seealso{ricedeco}
