Large numerator and denominator in symbolic matrix inverse?

Hi Mathworks/MATLAB gurus - Happy Thanksgiving to all.

I'm an aerospace professor, and I'm trying to automate the writing of exam questions for my finals. One of the things that I've never particularly been any good at in MATLAB is the handling of symbolic expressions. Fundamentally, I've got a state-space system with an [A] and [B], and I'd like to develop the transfer functions for the system (just for state variables, so no [C] and [D] matrix for this case.

For my purposes, I'd like to produce all the intermediate steps, and I've previously managed to do this with Wolfram Alpha pretty well - see attached figure.

I've tried to do the same in MATLAB, but I cannot get it to yield sensible values - each element of my matrix has a large value in both the numerator and denominator. For example, this is a MnWE (minimum nonworking example) for what I'm talking about

Alon = [-0.0148000000000000,-0.0294562647754137,0,-9.80665000000000;
    -0.160000000000000,-0.519148936170213,128.930400000000,0;
    0.00189357979188772,-0.0429153529115032,-0.874000000000000,0;
    0,0,1,0];


syms s

% Inverse of sI - A - full form
invA = inv(s*eye(size(Alon)) - Alon)
vpa(invA, 4)

Produces

[ (5.907e+18*(20.0*s + 9.0))/(1.181e+20*s^2 + 7.059e+19*s + 1.111e+21),                       -1.523e+22/(1.181e+20*s^2 + 7.059e+19*s + 1.111e+21)]
[                  8.554e+18/(1.181e+20*s^2 + 7.059e+19*s + 1.111e+21), (5.586e+15*(21150.0*s + 3121.0))/(1.181e+20*s^2 + 7.059e+19*s + 1.111e+21)]

And I cannot seem to get MATLAB to factorise the output for me to a sensible value. I suspect I'm not using some common function, or I'm ging about this the wrong way.

How can I get the output from MATLAB to be in a usable form like that from Mathematica?

Thanks in advance,

Harry
