In studies and analyses, a seven parameter model of a bone from the mechanical response tissue analyzer (MRTA) method, offering an approach to separate the effects of the soft tissue and bone, is employed within the frequency range of 400-6000 . The study results showed adequacy and appropriateness of applying MATLAB tools for curve fitting and determining mechanical properties of human bones in-vivo studies based on measured data of complex number valued frequency response functions and fitted data with a coefficient of determination of R2 = 0.956 …0.988.}, }
