Hi,
I wrote the following code for this equation :
M=(1/K)*sum(zkd*zkd'),and it's running with out errors ,but all the elements in matrix M (1000*1000) are of the same value (1.1180e+001),and Mz is just one single value (1.7619e+001)despite it should be (1000*1000).Can anybody help,please? clear all; clc load lab2_data; x = radar_noise; % input signal
K = 1000; % K CAPITAL is Block Size
L = length(x) - mod(length(x),K); % only full blocks
zkd = reshape(x(1:L), K, []); M=zeros(K,K); % M ZEROS covariance matrix L*L
for i=1:size(zkd,1); % LOOP covariance matrix calculation
Mz=zkd(i,:)*zkd(i,:)'; %
M=M+Mz; end M=M/K;
