z = zeros(1000, 22);
x = rand(1000, 22);
lamda = rand();
for k = 2 : 1000
z(k, :) = lamda * x(k, :) + (1-lamda) * z(k-1, :);
end

Your first two lines of X from X.mat are the same. That cannot be explained with any lamda other than 0 .
Your other lines of expected output cannot be explained with lamda = 0.03 : they all require lamda = 1.0003
Even then your expected outputs are frequently wrong in the 4th digit.
See attached, which is configured for 1.0003

z(1) = rand();
x = randn(1,1000);
lamda = rand();
for k = 2 : 1000
z(k)=lamda*x(k)+(1-lamda)*z(k-1);
end
