This is matlab please help me

The Golden Ratio psi can be expressed as an infinite continued fraction. Write the recursive function which gives the n-th approximation of the golden ratio. Psi = 1 at n = 1 Evaluate golden ratio for n = 1, n = 5, n = 10 and n = 100. create anonymous function to calculate equation: f(x) = 3 cuberoot log (x^2 + 1) x = 1, -9.3, sin (pi/3) f(x, y) = cos (2x^2 + 1) + sin^2(y^3) x=0.5, pi/3, -0.3 y = -1.1, pi/5, 1.7 The Golden Ratio psi can be expressed as an infinite continued fraction.
