| Dear All, I am working on the solution of an ordinary differential equation. Among others related to a given Ansatz I get a long set of sums I want to sort and order in dependency of terms like ((x/(-1 + x))^(expnt) with the exponents... |
| Dear all, I got a set of coupled Second Order Differential Equations (ODEs). To go on with a solution I need to convert the set of ODEs into a matrices equation. Now I need to grab the factors of the ODEs to put them into a matrix. Let us... |
