% ConvEncode encodes a NSC or RSC convolutional code with a tail.
%
% The calling syntax is:
%     [output] = ConvEncode(input, g_encoder, [code_type] )
%
%     output = code word
%
%     Required inputs:
%     input  = data word
%     g_encoder = generator matrix for convolutional code
%                 (If RSC, then feedback polynomial is first)
%
%	  Optional inputs:
%	  code_type = 0 for recursive systematic convolutional (RSC) code (default)
%               = 1 for non-systematic convolutional (NSC) code
%               = 2 for tail-biting NSC code
