In MATLAB the function padarray can be called with 3 arguments:

padarray(A, padsize, direction)

as well as 4 arguments:

padarray(A, padsize, padval, direction)


Example:
A = ones(4,4);
B = padarray(A,[2 0],'pre')
B =
     0     0     0     0
     0     0     0     0
     1     1     1     1
     1     1     1     1
     1     1     1     1
     1     1     1     1


The Octave code doesn't detect the 3-argument usage. Simple fix is to handle
another nargin case, added in *bold*.

-----------------------------------------------------------------
function B = padarray(A, padsize, padval, direction)

% Check parameters
if (nargin<2 || nargin>4)
    usage ("B = padarray(A, padsize [, padval] [, direction])");
end
if (nargin<3)
    padval=0;
end
*if (nargin==3) && ischar(padval)*
    *direction = padval;*
    *padval = 0;*
*else*if (nargin<4)
    direction='both';
end
