plus, f+g (symbolic addition)
minus, f-g (symbolic subtraction)
uminus, -f (symbolic negation)
times, f.*g (symbolic element-by-element multiplication)
power, f.^n (element-by-element powers)
prod (product of the elements)
sum (sum of the elements)

### Matrix manipuation

mtimes, f*g (symbolic matrix multiplication)
mpower, f^n (symbolic matrix power)
transpose, f.' (symbolic matrix transpose)
