How to sample and process signals of a given length in Simulink

I have to calculate the correlation of a signal x in Simulink:

Exx = 0;
for t=1:size(x,1)
    Exx = Exx + x(:,t)*x(:,t)';
end
Exx = Exx/size(x,1)

where x(:,t) corresponds n signal values measured at time t.

If this is to be done in Simulink, do I have to use the embedded Matlab function, or is there a more elegant way?

Thanks :)

To sample the signals use Weighted Sample Time block from simulink, there might be more options inside the signal processing library.

Use the Autocorrelation block, or follow the diagram description in the block documentation to implement your own.

Great thanks!
