MATLAB: Summation with resultant vector’s index as upper limit

sum

Hello,

I'm trying to write this summation in Matlab

I couldn't find any example of this anywhere, maybe someone can help me with the syntax here.

Just verify once if this is the formula that you needed. You would have to define K, b and n beforehand.

symsum((d(k).*symsum((K(l)*((sin(b(n-1))).^(2.*l))),l,0,(1-k))),k,1,n)

function B = movSum(A,n,m)
B=A;
for k=2:n
    B=[B;zeros(m,1)]+[zeros((k-1)*m,1);A];
end
end
