MATLAB: A recursive matrix sum

Question

Hey

I wrote a function that gives u the sum of the matrix. I try to write it with rerursive, but it doen't get well. i need an explanation..

this is my code –

function total=ff(l)
total = 0;
for i = 1:numel(l)
  total = total+l(i);
end

any help?

Answer 1

You function is not recursive

function total=ff(l)
lp=l(:);
if numel(l) == 1
    total = l(1);
else
    total = lp(end) + ff(lp(1:end-1));
end
end
