Fractals from the Lorenz Equations Determine the fractal that arises from using Newton's method to compute the fixed-point solutions of the Lorenz equations. Use the parameter values r = 28, = 10 and B=8/3. Initial values (x) are taken on a grid in the x-z plane with always yo = 3√2. For assessment purposes, the computational grid and the graphics code will be given in the Learner Template. To pass the assessment, every pixel in your figure needs to be colored correctly. (Hint: Some grid points may require as many as 33 Newton iterations to converge while others may require as few as three. Unfortunately, if you uniformly use 33 Newton iterations at every grid point, the MATLAB Grader may time out. You can accelerate your code by using a while loop instead of a for loop.)
