I need help with a MATLAB code. I am trying to implement algorithm 3 and 4 as shown in the image. I am getting some size errors. Can you help me fix the code. clc; clear all;     % Define initial conditions and parameters r0 = [1000, 0, 0]; % Initial position in meters v0 = [0, 10, 0]; % Initial velocity in m/s m0 = 1000; % Initial mass in kg z0 = log(m0); % Initial mass logarithm   a0 = [0, 0, 1]; % Initial thrust direction in m/s^2 (thrust in z-direction) sigma0 = 0.1; % Initial thrust magnitude divided by mass   % Initial state vector x0 = [r0, v0, z0] x0 = [r0, v0, z0];   % Initial control input u0 = [a0, sigma0] u0 = [a0, sigma0];   % Time span for integration t0 = 0; % Initial time tf = 10; % Final time N = 100; % Number of time steps dt = (tf - t0) / N; % Time step size t_span = linspace(t0, tf, N); % Discretized time vector   % Solve the system of equations using ode45 [t, Y] = ode45(@(t, Y) EoMwithDiscreteMatrix(t, Y, u0, x0, t0, tf), t_span, x0);   % Compute the matrices A_k,…
