Figure 1
Interpolation of a smooth function using both double (F64) and quadruple (F128) precision. The script condVaccury.m produces the plots. Left: accuracy versus the shape parameter. Right: condition number of the system matrix versus the shape parameter.
Figure 2
Interpolation with (green solid) and without (blue dashed) regularization. The script mdiRegularization.m produces the plots. Left: accuracy versus the shape parameter. Right: system matrix condition versus the shape parameter.
Figure 3
1000 centers on the unit circle. Left: Hammersley points. Right: clustered Hamersley points.
Figure 4
Center distributions that result in centrosymmetric distance matrices. Left: 2000 centers based on clustered Hammersley points that have been extended centro symmetrically about the x axis. Right: 2524 centers on a domain enclosed by the curve that result in centrosymmetric distance matrices.
