You are required in this Assignment to develop a program using Matlab applying the FletcherReeves method of the Conjugate Gradient to calculate the unconstrained minimum of the following multivariable functions: 1. Rosenbrock's parabolic valley: f(x1,x2)x0=100(x2x12)2+(1x1)2=[1.20]t 2. Wood's function: f(x1,x2,x3,x4)x0=[10(x2x12)]2+(1x1)2+90(x4x32)2+(1x3)2=[3131]t+10(x2+x42)2+0.1(x2x4) 3. A nonlinear function of three variables: f(x1,x2,x3)=1+(x1x2)21+sin(21x2x3)+exp[(x2x1+x32)2]x0=[012]t 4. Freudenstein and Roth function: f(x1,x2)x0={13+x1+[(5x2)x22]x2}2+{29+x1+[(x2+1)x214]x2}2=[0.52]t 5. A quartic function: f(x1,x2)x0=x142x2x12+x22+x122x1+5=[00]t You must submit your report covering minimum the following items: 1. The Matlab source code. 2. The Contour-plot (when applies) showing the successive points. 3. Table of iterations comprising: iteration number, x value, f(x) value and f(x)
