Issue with integration using trapz

Hello,

I'm trying to implement integration using trapz. But the resultant quantity after integration is negligibly small and doesn't increment. Am I doing something wrong which is confusing me.

Can you see and advice me the chnages if any.

 num=15;
    Iq(1)=eps;
    for i=2:11
    Iq(i)=trapz(X(1:i),X(1:i).*jd0.*(1-(X(1:i)-x0).^2).^num);
    end

Here, x0=1

rgds,

rc

we cannot run your code

please provide the missing data (X, jd0,...)

what is the expected result ?

To avoid the loop, you can use "cumtrapz" instead of "trapz".

problem solved ?
