MATLAB: How to perform symbolic factorial

factorialsymbolic

I am trying to generate symbolic sums that represent, say, taylor series of some function. This series includes a factorial term but I have been unable to implement it. I may have something like: syms x n f=1/(1-x^4) f2=symsum((1/factorial(n))*f^(n),n,0,10) where f^(n) is the "nth" derivative of f. "factorial(n)" is a placeholder to illustrate what I am trying to accomplish. Any advice would be greatly appreciated. By the way, I am aware of the "Taylor" function. The above example was used to point out my problem area.

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)
