.SH DESCRIPTION |
| 66 |
|
the four components, and if the first component |
| 67 |
|
is isotropic, all components must be isotropic. |
| 68 |
|
A similar rule holds for anisotropic inputs. |
| 69 |
+ |
The |
| 70 |
+ |
.I \-l |
| 71 |
+ |
option may be used to specify the maximum number of lobes in any |
| 72 |
+ |
interpolated radial basis function. |
| 73 |
+ |
The default value is 15000, which generally keeps the interpolation tractable. |
| 74 |
+ |
Setting the value to 0 turns off this limit. |
