Some functions can be useful as standalone

drawPatternsIJ(WT,i,j,path_pattern_save);

shows scattering of WT type (e.g. PP, PSV, SVSH etc.) on perturbation of C_ij element of stiffness matrix and saves eps to path_pattern_save.

drawPattern(WT,Cij,denFlag,patternType)

draws the radiation pattern of given type in 3D view (parmetrized by the vector g pointing towards geophone) for preliminarily assembled Cij matrix. Figure 3 is created with these finctions:

simpleRes(Cij, WT, KzMin, KzMax, dKz, phiMax, dPhi, denFlag)

computes the resolution in wavenumber(K_z)-azimuth domain (Figure 7).

resFunc(parSET)

quantifies resolution for all elastic parameters and finds the null-space for given scattering type
