MATLAB HELP ( use Matlab code for the answer please!)

2. Simultaneous Nonlinear Equations Determine the roots of the simultaneous nonlinear equations y y y = = = x2 +1 +23 2.2. cos x x y z (2) Employ the initial guess of x = y = 2 = 1.2. Determine refined estimates with three-equations Newton-Raphson method. - save the x on EX2_15.dat file - save the y on EX2_16.dat file - save the z on EX2_17.dat file - save the number of iteration on EX2_18.dat file
