function to fit Bingham parameters

Description

confidence ellipse for the mean direction based on Tanaka (1999) https://doi.org/10.1186/BF03351601

Syntax

BS2 = BinghamS2.fit(v)

Input

v vector3d

Output

BS2 BinghamS2

Options

ConfElli confidence level p (default at 0.95)

Example

% simulate some directions
odf = unimodalODF(quaternion.id,'halfwidth',10*degree);
N = 100;
v = odf.discreteSample(N) .* ...
rotation.byAxisAngle(vector3d.X,rand(N,1)*2*pi) * vector3d.Y;
Warning: Possibly applying an orientation to an object in specimen
coordinates!
% fit a Bingham distribution
S2F = BinghamS2.fit(v)
S2F = BinghamS2
