The symbolic toolbox solve() routine has many many parts to it, a major programming effort, as it has to deal with a large number of different functions -- it is _not_ restricted to polynomials.
Generally speaking, roots of polynomials are usually found in symbolic packages by looking for Groebner Basis. (Unfortunately I never did figure out what a Groebner Basis _is_ or how to find one...)

Hi, you cannot. That is a built-in (compiled) function. The source code for the function and others like is not shipped with MATLAB.

type min
type solve
type diff
For the version I am using, the response is:
>> type min
'min' is a built-in function.
>> type solve
??? Error using ==> type
File 'solve' not found.
>> type diff
'diff' is a built-in function.
which is expected: min and diff are not implemented in the MATLAB language, and solve is part of a toolbox that I do not have.
