function value = i4_pochhammer ( i, j )

%% I4_POCHHAMMER returns the value of ( I * (I+1) * ... * (J-1) * J ).
%
%  Discussion:
%
%    Pochhammer's symbol (A)_N is the value
%
%      (A)_N = Gamma ( A + N ) / Gamma ( A )
%
%    or, for integer arguments,
%
%      (I)_N = I * ( I + 1 ) * ... * ( I + N - 1 )
