steepestDescent

(method of S2FunHarmonicSym)

calculates the minimum of a spherical harminc

Syntax

[f,pos] = steepestDescent(sF) % the position where the minimum is atained
[f,pos] = steepestDescent(sF,'numLocal',5) % the 5 largest local minima
% with all options
[f,pos] = steepestDescent(sF, 'startingnodes')

Output

f

double

pos
