Hi! Im using Matlab version 7.9.0(R2009b) and i would like to sum e.g. first 10 terms of expression c_i*x^i, where c_i should be obtained symbolically. how should i do that, so that this expression is dependent on x / function of x (so when i enter exact number for x, i get real number - not expression with c_i).
No products are associated with this question.
c=sym('c',[1 10]) x=sym('x') f=@(x,n)sum(c(1:n).*x.^(1:n)) f(x,5)
