SpletThe inversion process essentially outputs the parameter pair () that maximizes the semblance (ρ) for the given input parameters and waveforms and the dispersion model. Fig. A5.8 shows the inversion result in the form of the dispersive semblance projection log for field data along with the input waveforms and the dispersion. SpletExistence of Generalized Inverses Let EAP = I r K O O ; r = rank(A) min(n;m); be the reduced row echelon form of A 2Cm n (see ﬁrst year Linear Algebra course). Any X given by X = P I r O O L E for some L 2C(n r) (m r) satisﬁes AXA = A. I For every A there exist one or more generalized inverses.
