Real-time feature extractor implementation

Dear Matlab users,

I would like to process a signal in real time, the signal is provided by another block on simulink, the type of processing I want used by applying the following formula:

%% Input : Ia a vector of n*1 
%% Output : Sa a vector of ne*1 
l = length(Ia); 

Unrecognized function or variable 'Ia'.

N = 1000;  %%  Number of samples
ne = (l-mod(l,N))/N; %% Number of iterations to balance Ia

n1 = 0;
for i = 1:ne
    
    a = 0;
    
    for j = n1+1:n1+N-mod(l,N)
        
        a = Ia(j) +a;
    end
    n1 = n1+N;
    
    Sa(i) = a;
    
end

Hi Saad. You can use a MATLAB Function block in Simulink which performs the custom processing you want. The following articles may help you further with this.
