Hello, Doug!
Some examples below:
1)
>> syms x y
>> S=(x^2+xexp(x))*(x+3)
S = (sym)
/ 2 x\
(x + 3)*\x + x  e /
>> F=collect(S)
error: 'collect' undefined near line 1 column 3
>>
it was expected F=x^3+4*x^2+(exp(x)+3)*x3*exp(x)
2)
>> syms x y
>> S=x*(x*(x8)+10)5
S = (sym) x*(x*(x  8) + 10)  5
>> SA=simplify(S)
SA = (sym) x*(x*(x  8) + 10)  5
>>
it was expected SA=x^38*x^2+10*x5
3)
>> sym x
ans = (sym) x
>> s=(x^34*x^2+16*x)/(x^3+64)
s = (sym)
3 2
x  4*x + 16*x

3
x + 64
>> F=simple(S)
error: 'simple' undefined near line 1 column 3
>>
it was expected F=x/(x+4)
I'll appreciate any assistance!
Thanks,
Paulo Roberto.
