For summing definite series, symsum can be faster than sum. For summing an indefinite series, you can only use symsum . You can demonstrate that symsum can be faster than sum by summing a large definite series such as S = ∑ k = 1 100000 k 2 .
I want to compute the following infinite sum in Matlab, for a given x and tau: I tried the following code, given x=0.5 and tau=1: symsum((8/pi/pi)*sin(n*pi*0.5)*sin(n*pi*0.5)*exp(-n*n*pi*pi)/n/n,1,inf)
5 maj 2015 · how can I find the sum of infinite series with nth term as an= 1/[(2n-1)(2n+1)]^2. Also how many terms are needed to obtain an accuracy of 1e-12?
13 lip 2018 · Let $u(x)$ be a function of $x$ defined as an infinite series (below). I would like to compute $u$ for a certain range of $x$. Here are the values of the parameters, $\alpha=0.5$, $K_{\alpha} = 1$, $t = 10$, and $-40<x<40$.
