Create a SimTKMultivariatePolynomial object.
This implementation assumes a maximum of four dimensions and allows computation of order one derivatives only.
- Parameters
-
coefficients the polynomial coefficients in order of ascending powers starting from the last dependent component. For a polynomial of third order dependent on three components (X, Y, Z), the order is a follows: Index | X Y Z 0 | 0 0 0 1 | 0 0 1 2 | 0 0 2 3 | 0 0 3 4 | 0 1 0 5 | 0 1 1 6 | 0 1 2 7 | 0 2 0 8 | 0 2 1 9 | 0 3 0 10 | 1 0 0 11 | 1 0 1 12 | 1 0 2 13 | 1 1 0 14 | 1 1 1 15 | 1 2 0 16 | 2 0 0 17 | 2 0 1 18 | 2 1 0 19 | 3 0 0
Assuming c6 the index 6 coefficient, the corresponding term is Y Z^2.dimension the number of dependent components order the polynomial order
