How to speed the code? It does not want to end processing!!!!

R = length(lambda) ;

Unrecognized function or variable 'lambda'.

T = size(X,2) ;
time_dmd = zeros(T-1,R);
for iter = 1:T-1
    for p = 1:R
        time_dmd(iter,p) = b(p)*(exp(omega(p)*t(iter)));
        Xdm(:,iter,p) = real(Phi(:,p)*(b(p).*exp(omega(p)*t(iter))));
    end
end

Well I can see a few obvious problems, but the most obvious problem is that that this isn't even complete code.

It's a bit hard to troubleshoot something If it's unknown what size anything is or if the code even works.

Here's my guess.

% assuming b,omega,t are all row vectors
% width of Phi is equal to length of b,omega
time_dmd = b.*exp(omega.*reshape(t(1:end-1),[],1))
Xdm = permute(Phi,[3 2 1]).*time_dmd;
Xdm = real(permute(Xdm,[3 1 2]));

What is the size and class of the variable x that you load from your MAT-file? You can display this information using the whos function.

x = magic(4);
whos x

  Name      Size            Bytes  Class     Attributes

  x         4x4               128  double

It's not complete. You didn't attach 'model11.mat'
