Imatlak code] Implement an autocorrelation function estimator for an arbitrary stochastic process. For the developed effect, the function "autocorrelation", so that: B.taul=autocorrelation (X, t, to), where X is a matrix that in each column contains an Implementation of the process X(t). Consider completing the following function: function [R, tau) = autocorrelation (X, t, to) % [R, tau) = autocorrelation (X, t, to) % Estimate the autocorrelation function R(t0,t0 + tau) of a stochastic process X % Input variables % X: matrix that in each column contains an implementation of the process X(t) %t: vector that defines the time evolution of the samples of X (t). % to: Instant of time taken as a reference for the calculation of the function R % Output variables % R:vector that contains the evolution of the autocorrelation function of the process X(t) % tau: vector that defines the relative temporal separation of the samples with respect to the reference to. if nargin
