Details:


I just finished porting a complex model of an MPEG-2 video encoder originally
written in Matlab. When executed on GNU Octave the model produced syntax
errors in the output video stream. I traced this to the dec2bin() function.

Matlab: dec2bin(0,0) returns ''
Octave: dec2bin(0,0) returns '0'

When using dec2bin to produce character strings by concatenation, extra 0 bits
were appearing in the result.
