WebThe module defines the following three functions: scipy.optimize.bisect. scipy.optimize.fmin. scipy.optimize.newton. Note that routines that work with user-defined functions still have to call the underlying python code, and therefore, gains in speed are not as significant as with other vectorised operations. As a rule of thumb, a factor of two ...
