writing this equation double summation by using matlab

What have you tried so far? This looks like homework, why don't you try to do it yourself and ask a specific question instead of dumping it on a forum.

hey Rik,

Thanks for your reply,

This is not homework, despite what you indicated. I attempted to use Excel to get a number for this problem, but I would then compare that number with the output of Matlab programming. I would be grateful if you could assist me. Other methods do not disregard your inquiry.

example:

b_w^2 = sum( (diff(q_o)./diff(X)).^2.*b(1:end-1) ) + sum(sum(diff(q_o)./diff(X)'.*diff(q_o)./diff(X),2),1).*b(2:end);

Many thanks Cui,
