Compute the index of the first coefficient with the given order in a packed 2-d polynomial coefficient array.
This defines the ordering as
(or the same with indices swapped).

void lsst::meas::astrom::detail::computePowers | ( | Eigen::VectorXd & | r, |
double | x | ||
) |
Fill an array with integer powers of x, so \($r[n] == r^n\).
When multiple powers are needed, this should be signficantly faster than repeated calls to std::pow().
