Let N be an integer. 

 

For each pair of integers (n,m) where 1<= n,m <= N, we have a variable f_{n,m}(t). 

 

Then for these we have a system of ODEs 

 

d/dt f_{n,m}(t) = \sum_{n', m'} f_m'n' * f_m''n'' * (m'n'' - m''n') 

 

where m''=m-m', n''=n=n', and the sum is simply over for all pairs (n',m'). 

 

I simply do not know how to put these set of equations into Maple in a nice way. 

 

I will really appreciate any help!
