CRC-5 in MATLAB

Question

How to encode/decode CRC-5-EPC (x^5+x^3+1) in MATLAB?

I've tried:

code = encode(msg,n,k,'cyclic/binary', [1,0,1,0,0,1]);

But it returns:

The generator polynomial P cannot produce a cyclic code generator matrix.

Answer 1

Maybe you should use crc.generator(doc) instead of encode :

 h = crc.generator([1,0,1,0,0,1])
 code = generate(gen, msg);

Answer 2

From http://www.mathworks.co.uk/help/toolbox/comm/ref/encode.html (emphasis is mine):

code = encode(msg,n,k,'cyclic/fmt',genpoly) encodes msg and creates a systematic cyclic code. genpoly is a row vector that gives the coefficients, in order of ascending powers, of the binary generator polynomial.
