d,
    the normals will be approximated. The array returned by
    fprime_ieqcons should be sized as ( len(ieqcons), len(x0) ).
args : sequence, optional
    Additional arguments passed to func and fprime.
iter : int, optional
    The maximum number of iterations.
acc : float, optional
    Requested accuracy.
iprint : int, optional
    The verbosity of fmin_slsqp :

    * iprint <= 0 : Silent operation
    * iprint == 1 : Print summary upon completion (default)
    * iprint >= 2 : Print status of each iterate and summary
disp : int, optional
    Overrides the iprint interface (preferred).
full_output : bool, optional
    If False, return only the minimizer of func (default).
    Otherwise, output final objective function and summary
    information.
epsilon : float, optional
    The step size for finite-difference derivative estimates.
callback : callable, optional
    Called after each iteration, as ``callback(x)``, where ``x`` is the
    current parameter vector.

Returns
-------
out : ndarray of float
    The final minimizer of func.
fx : ndarray of float, if full_output is true
    The final value of the objective function.
its : int, if full_output is true
    The number of iterations.
imode : int, if full_output is true
    The exit mode from the optimizer (see below).
smode : string, if full_output is true
    Message describing the exit mode from the optimizer.

--------
minimize: Interface to minimization algorithms for multivariate
    functions. See the 'SLSQP' `method` in particular.

Notes
-----
Exit modes are defined as follows:

- ``-1`` : Gradient evaluation required (g & a)
- ``0`` : Optimization terminated successfully
- ``1`` : Function evaluation required (f & c)
- ``2`` : More equality constraints than independent variables
- ``3`` : More than 3*n iterations in LSQ subproblem
- ``4`` : Inequality constraints incompatible
- ``5`` : Singular matrix E in LSQ subproblem
- ``6`` : Singular matrix C in LSQ subproblem
- ``7`` : Rank-deficient equality constraint subproblem HFTI
- ``8`` : Positive directional derivative for linesearch
- ``9`` : Iteration limit reached
