Curve Math Operations - Interpolation
Use interpolation to resample your data at an even interval. Interpolation is intended to fit more data points to a small number of existing data points, but you may increase or decrease the number of points. Based on the existing range and the number of points specified, if a new value on the abscissa (that is, "x" value) is computed, a corresponding new value for the ordinate (that is, "y" value) is computed based on the interpolation method chosen.
The data is always displayed using an AKIMA spline.
For the option: | Do the following: |
|---|
Method | Select one of the following interpolation options: akima, linear, cubic, spline, notaknot, and hermite. For more information on spline methods, see the Adams Solver online help, and Numerical Recipes in C, published by Cambridge University Press. |
Points | Enter the number of points you want to have in the interpolated spline. |
