the minimum of a function on SO(3) or the sphere, the value and the position, numLocal local minima; with a second function or a number the pointwise minimum; with axis= along an axis of a list; MATLAB’s min

Syntax

value, ori = min(odf)

The global minimum and where it is.

values, oris = min(odf, numLocal=3)

Three local minima.

f = min(odf, 0)

The pointwise minimum with a number.

Description

The minimum is the maximum of -f, the keywords resolution, accuracy and startingNodes as for max.

Input

f SO3Fun, S2Fun or S1Fun; a second function or a number for the pointwise minimum

Keywords

keyword default description
numLocal 1 the number of local minima returned

Output

value the smallest value, or numLocal values in ascending order
ori the position: orientation, vector3d, or the angle on the circle
