ex03_interpolation
This example resamples one irregularly spaced text series onto the regular
axis -T0/10/0.05. It compares all interpolation methods available through
the -S option:
-Sa Akima spline
-Sc Cubic spline
-Se Step-up
-Sl Linear interpolation
-Sn Nearest point
-Ss0.5 Smoothing spline with a fit parameter of 0.5
Linear interpolation is the default when -S is omitted. The script verifies
that the default output is identical to the result from explicit -Sl.
Run:
./ex03_interpolation.sh
The script creates ex03_interpolation.png and ex03_interpolation.pdf.
