MATLAB symbolic derivatives not simplifying automatically

[ergospherical]

I am using MATLAB to compute a few symbolic derivatives. The outputs are correct (I've checked a few of them) but usually long and never simplified (even when "obvious" simplifications are possible, i.e. combining terms, cancelling things). Is there a way to get MATLAB to simplify symbolic expressions?

I found the "simplify" operation - doesn't seem to do much...

How about mathematica?

Or this from matlab

Actually works a lot better - might switch to this instead. Cheers!

Mathematica is better if you need symbolic computation. MATLAB is more for numerical computation.
