Spline

Spline is a powerful software that excels at interpolating an Akima-spline through a series of designated points. What sets it apart from ordinary splines is its ability to approximate a manually drawn curve with greater accuracy. However, it is important to note that the second derivation is not continuous, which some users may find limiting.

The software itself is easy to use, with a simple command line interface. Users can input a variety of parameters, such as setting the lower and upper x-limits, and specifying the number of intervals between the two limits. Additionally, the software offers an automatic option for supplying abscissas if needed.

For those who need assistance, the software offers a detailed help section that can be accessed with the -h or --help command. Additionally, if you need to access the licensing terms, that information is also easily accessible with the -W or --warranty command.

If you are looking for a powerful software that can handle interpolation, Spline is definitely worth considering. With its ability to accurately approximate manually drawn curves and its user-friendly interface, Spline is sure to prove useful to a wide range of users.
