Summary |
0000634: FIXED: instability in PolynomialBar2Pow() function |
|
Description |
Function accumulated rounding errors when magnitude of abscissas was too large or too small (larger or smaller than S - scale parameter). The problem was in the inadequate placement of sampling points - too spread or too close. Now algorithm places sampling points according to spread of nodes of barycentric model, which results in more stable algorithm. |
