PDF to ODF inversion
calcFEMODF is one of the main function of the MTEX toolbox. It estimates an ODF from given Polefigure intensities by fitting an ODF that consists of a large number of unimodal ODFs to the data. It does so by minimizing a least squares functional. The command calcODF supports automatic ghost correction and the zero range method. The function calcFEMODF has several options to control convergence, resolution, smoothing, etc. See below for a complete description.
Syntax
[odf,alpha] = calcFEMODF(pf,varargin)Input
| pf | PoleFigure |
Output
| odf | reconstructed @FEMODF |
| alpha | scaling factors, calculated during reconstruction |
Options
| resolution | localization grid for the ansatz fucntions (default = 3/2 resolution(pf)) |
| iterMax | maximum number of iterations (default = 11) |
| regularisation | weighting coefficient lambda (default = 0) |
Flags
| zeroRange | apply zero range method (default = ) |
| noGhostCorrection | omit ghost correction |
