OCTAVE_KD4kvmb

This Octave program combines the C1, stiffness and C2, damping wave equation coefficients (Equation 4) determined from body wave dispersion inversion (CAINV3, 8.2.7) with porosity and a desired frequency to return solutions for the Kelvin-Voigt (KV) damping ratio. There will be up to two possible solutions. The likely solution is the coupled solution, but the program returns the uncoupled solution as well. The coupled solution is more likely since most earth materials are not permeable enough to result in the uncoupled solution.
