factorialfalling-factorialmultiplicationpochhammer

I would like to know if there is any function that gives me the falling factorial, i.e,

I have seen that there exists the Pochhammer function that gives you

Any help?

prod(x-a+1:x)

The MuPad factorial function name is fact() . This does not, however, appear to be exposed at the Matlab level, so you might need to use, (e.g.,)

f2=symsum((1/sym('factorial(n)'))*f^(n),n,0,10)

syms x
N=4;
f(x)=sum(x.^(0:N))
