I would like calculate the following in matlab. X and k are arrays sized (1,N).
I have been using "symsum", but it is very slow for large N values:
symsum((X*Y)./((1+Z).^(A+k*B)),k,1,K));
So my question is, how can I best calculate this in matlab?

An alternative to using symsum to sum long long series is use integration rather. MATLAB does provide int function for doing definite and indefinite function.
