toplinmin_func

result = linmin_func(lambda [, point=point] [, dir=dir] [, _extra=_extra] [, linfunc=linfunc])

Parameters

lambda in required

Position along the line

Keywords

point in optional

The starting point for the line

dir in optional

A vector giving the direction of the line

_extra in optional

Any extra keywords are passed to linfunc.

linfunc in optional

A user written function to minimize. Evaluated at(point + lambda * dir)

Numerical Recipes

result = linmin(func, point, dir [, step=step] [, dist=dist] [, _extra=_extra] [, verbose=verbose])

Return value

Parameters

func in required

point, dir, fmin. These keywords are used internally to linmin.

point in required

A reference point on the line to minimize func over. An n-element array. This is updated with the new minimum upon completion.

dir in required

The direction of the line to minimize. An n-element array.

Keywords

step in optional

The initial stepsize to take when bracketing the minimum. This sets the size-scale of the function, and can be used to help the linmin find the minimum closest to point. Defaults to 1.

dist in optional

A keyword to hold the distance between point and the minimum.

_extra in optional

Any extra keywords will be passed to func

verbose in optional

Control the amount of textual output. Verbosity is handled via the VERBIAGE program - see documentation for details.
