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;% fit a Bingham distribution
S2F = BinghamS2.fit(v)S2F = BinghamS2 (y↑→x)
