Can you please write a matlab code for the given question?

When laser light is incident on tissue, the tissue acts as a transfer medium that can reflect, absorb, scatter, and transmit various portions of the incident wave of radiation. Diffusion equations can be constructed to describe the propagation of light intensity as a function of distance. Imagine an isotropic light source from a laser fiber within a tissue that can both absorb and scatter light. If the tissue acts as an infinite medium, under conditions of predominant scattering, the light fluence rate (in W/cm2) at a large distance r from the fiber can be shown to be: where the penetration depth, -ND/Ha, and Ha s the tissue absorption coefficient. The anisotropy of the medium, g-o9, absorption coefficient,Ha-0.1cm-1, scattering coefficient,H5-100cm-1. Find the distance away from the point source of laser where the light intensity (r) drops to 30% of that of the source. Note that Use Secant Method with the two initial estimates as Xi-1-0.12 and x,-0.13. Use e,-0.01% for this problem. Besides functions abs (), exp), sqrt , and fprintfo, do not use any other built-in functions. Also, Anonymous function (fhandle - (arglist) expression) is not allowable. As output, print a table on the Command Window with the results that look like: f (xi-1) Ea xi 0.030012 0.070000 3.1921e-003 7.8146e-002 133.2437 Iteration xi-1 f (xi) When laser light is incident on tissue, the tissue acts as a transfer medium that can reflect, absorb, scatter, and transmit various portions of the incident wave of radiation.
