Function minimization [message #53454]

I wish to minimize a function, that is, to find the abscissa
corresponding to
the minimum function value. The IDL procedure minF_parabolic exists
for this express purpose, but the discussion of how to implement it
is
frustratingly vague, e.g.,

; Calling mechanism should be: F = func_name( px )
; where:
; px = scalar or vector of independent
variables, input.
; F = scalar value of function at px.

I have been singularly unsuccessful on implementing a procedure/
function which implements minF_parabolic to minimize a quadratic
function. Specifically, I am not at all clear how any function gets
minimized if only a scalar - px - is being passed. Wouldn't one want
to pass an array of independent variables?

I'd appereciate any specific examples of implementation of this
procedure
