I need to calculate a values c2, c3, c4,..., using the equation:
where alpha and beta are the elements of a given vectors of length k. For each q i need to calculate the result. usually Cq will result zero, so i need to find what value of q will be different to zero. I think to do that thing in matlab is using while, but my problem is combine summatory and while in matlab.
for example
in this case the value of k is 2, aplying the equation above for each c2=c3=c4=0 except in c5 which means q=5, by the way values of q start from 2 and above.
Please help me.

You should be able to easily modify my answer to match your indexing.

I need to break the calculation when a cq is different to zero. I was thinking to use a while loop, to break the calculation when a cq is different to zero. I can use so sum((1:k) expression) inside the while I don’t know maybe can work. Thanks

C=@(q)sum((1:k).^q.*alpha)/factorial(q)-sum((1:k).^(q-1).*beta)/factorial(q-1);
q=1:100;
c=arrayfun(@(x)C(x),q);
plot(q,c);
