Description

This is a program to test the polynomial spline interpolation.

It just prints some function to stdout. You can look at the result using the following commands:

--------— snip --------— ./test_spline > spline.csv gnuplot

gnuplot> plot "spline.csv" using 1:2 w l ti "Curve", \ "spline.csv" using 1:3 w l ti "Derivative", \ "spline.csv" using 1:4 w p ti "Monotonical" --------— snap --------—
