moment_joint_upfactorial_from_negbinomial.m

function fp = moment_joint_upfactorial_from_negbinomial(bm)
% fp = moment_joint_upfactorial_from_negbinomial(bm)
%
% Converts joint negative-binomial moments into joint upward-factorial
% moments. Inverse of moment_joint_negbinomial_from_upfactorial.
%
% Input:
%   bm: array of size (n_1+1)x...x(n_d+1) holding the joint negative-binomial
%       moments, element (i_1+1,...,i_d+1) being the moment of
%       multi-order (i_1,...,i_d) and element 1 being 1
%
% Output:
%   fp: array of the same size holding the joint upward-factorial moments
