This is a signal processing toolbox function. It should go into
octave-forge instead. You also need to check error_state after
initializing the variables to see that a matrix has been read.

  Matrix sos( args(0).matrix_value() );
  ColumnVector x( args(1).vector_value() );
  if (error_state)
    {
       // The rest of the code
    }


This will prevent the code running after an error in reading the
argument list. Do you want to commit this to the octave-forge signal
toolbox?
