- Warning:
- See the Interpolation class for information about the required lifetime of the underlying data.

Constructor & Destructor Documentation
◆ BicubicSpline()
| BicubicSpline | ( | const I1 & | xBegin, |
| const I1 & | xEnd, | ||
| const I2 & | yBegin, | ||
| const I2 & | yEnd, | ||
| const M & | zData | ||
| ) |
- Precondition
- the \( x \) and \( y \) values must be sorted.
