returns the principalcomponents of grain polygon, without Holes
Syntax
[omega,a,b]= principalComponents(grains,varargin)Input
| grains | grain2d |
Output
| omega | angle of the ellipse |
| a | length largest axis |
| b | length smallest axis |
Options
| area | scale a,b such that the corresponding ellipse has the same area as the grain (default) |
| boundary | scale a,b such that the corresponding ellipse has the boundary length as the grain |
