I want to use a MATLAB system object for shortened Reed-Solomon code. This is my code (MATLAB R2015a):
N = 255; % code word length
K = 239; % message length
S = 152; % short message length
gp = rsgenpoly(N,K,[],0);
Enc = comm.RSEncoder('BitInput',true, ...
'CodewordLength', N, ...
'MessageLength', K, ...
'ShortMessageLengthSource', 'Property', ...
'ShortMessageLength', S, ...
'GeneratorPolynomialSource', 'Property', ...
'GeneratorPolynomial', gp, ...
'PrimitivePolynomialSource', 'Property', ...
'PrimitivePolynomial',[1 0 0 0 1 1 1 0 1]);
input = randi([0 1], 152*8 ,1);
coded = step(Enc,input);
But it gives the following error:
Error using zeros
Size inputs must be integers.
Error in comm.RSEncoder/setupImpl (line 446)
data = zeros(outputLength, 1);
Error in test (line 52)
coded = step(Enc,input);
Does anyone know what the problem is?
UPDATE
Apparently, there is a bug in RS encoder system object of the MATLAB R2015a. The code works with later releases of MATLAB.

This is a bug in RS encoder system object in MATLAB R2015a and it has been corrected in MATLAB R2016a. You can try the same and verify.
