Hi all,

I am having some problems when solving high order polynomials. When oders are 'high' and systems involve multiple variables, Maple is slow to do so.

See in worksheet for detailed codes.

slow.zip

kappa - gives the vector that i am interested in

sC - a reparameterisation which has 'summation' in it

Aim is to verify that it works (it should!)

I currently ask maple to solve the 'system' in terms of the original variables. It can be done (with a powerful computer and days of waiting), but takes a long time and sometimes, not working.

But is there a better way to substitue them into kappa and simplify? Faster and more efficient?
