Hello All,
I am trying to understand a piece of code I found but I am stuck on this
summation. This is part of a larger do loop over n.
UnderoverscriptBox[\(\[Sum]\), \(m = \(-10\)\),
\(10\)]\(\(eigenfunctionsort[n, j]\)[\([m + 11]\)]
Exp[I*2*\[Pi]*m*x/dp]\)\),{j,1,21}]
What I mainly do not understand is what is happening with the [m+11]. Is
that being multiplied with eigen function sort with each step in the sum,
or is that simply adding 11 to m at each step in the sum?
Thanks Ben
