We present a fast method for evaluating expressions of the form u j=∑ i= 1, i≠ j n α i x i− x j, for j= 1,…, n, where α i are real numbers, and x i are points in a compact interval of R. This expression can be viewed as representing the electrostatic potential generated by charges on a line in R 3. While fast algorithms for computing the electrostatic potential of general distributions of charges in R 3 exist, in a number of situations in computational physics it is useful to have a simple and extremely fast method for evaluating the potential of charges on a line; we present such a method in this paper, and report numerical results for several examples.
