# [SciPy-User] maximization functions

```Hello again Robert;

And thanks for that response!  Hope it's not asking for too much "hand
holding," since I don't quite understand it yet, but would you maybe offer
an example of what and how exactly to call from scipy if I have a function
to MAXimize that takes one variable (direct parabolic interpolation)
say between 0 and 1 with a precision of 0.01 up to 100 iterations?

Thanks again,

To convert a maximization problem to a minimization problem:

def func_to_minimize(x):
return -func_to_maximize(x)
