Note that it is a little slow, because every time a new Sum is produced, Mathematica tries to see if it can evaluate it. and it still works): In:= factorSum*x*y*b^i + y*c, i]] Sum :> Module, 1] ĮxpandSum := expr /. k 1 n a i is shorthand for there being a function f: N C where f ( i) a i and we are summing i N f ( i) which is a general case of S being a finite or countable set and we sum s S s (this assumes the countable sum converges and this would not be meaningful on any set where the sum doesnt) and. You can write similar code to reverse these operations. Tutorial for Mathematica & Wolfram Language. Calculate totals, sums, power series approximations.
#SUMMATION IN MATHEMATICA HOW TO#
Here's some quick code for taking common factors out of sums and expanding sums. It may look like a stupid question, but I was really confused by how double sums works in mathematica: After simplification, the function actually has nothing to do with n2 Also, when I manually calculate Kin 1,1, which is n1n21, it should be m1m20. How to build integer sequences and recursive sequences with lists. I assume that the indefinite sum that you're really interested in is more complicated than the example you provided. However, simple cases are easily programmed by hand. Mathematica does not have the (user facing) ability to do manipulations of unevaluated sums or integrals.
