This set of functions is used for anisotropic effective-medium modelling. Each function in this package has a description, explanations of inputs and outputs, and a list of relevant references.
File “Example.m” is the main driver Matlab script, which demonstrates the use of the functions.

Script Package – Functions
Returns components of stiffness tensor of a matrix of a VTI media with added impact of aligned elliptical inclusions.
Returns 1 if input stiffness moduli satisfy all physical constraintes, returns 0 if at least one of the constraints is violated.
Returns compliance/stiffness matrix of VTI media in a Voigt form assembled from vector of components organised as M = [m11 m33 m44 m66 m13] or does the reverse procedure if input is 6×6 matrix; M = S or C depending on parameter moduli_type.
Returns independent compliance moduli of VTI media if input is stiffness, or independent stiffness moduli if input is compliance.
Returns stiffness tensor of a composite media consisting background with elliptical inclusions in Voigt matrix form.
Is used to fit the experimental normalised ODF with Owens’s function, determined by parameter a.
Returnes normalised ODF in the format suitable for polycristal calculation script.
Determines Owens’s orientation distribution function.
Returns components of stiffness tensor of a matrix of a VTI media with removed impact of aligned elliptical inclusions.
Returns elastic moduli of reoriented VTI media depending on parameter “mode” using orientation parameters W200 and W400.
Returns elastic moduli of reoriented VTI media depending on parameter “mode” using orientation parameter a (Owens’s function).
Returns stiffness tensor (in Voigt matrix form) of a composite media consisting of elliptical inclusions.
Returnes coefficients W200 and W400 for ODF described by Owens’s function (parameter a).
