The BSpline is based on the code of Arkan (https://github.com/brainexcerpts/BSpline). The bsplines.hpp allows to compute
bspline functions and the first derivative. The spline.hpp allows to compute a quadratic spline function.
If you want to use the CLI and the jupyter notebook do as follow,
mkdir build
cd build
cmake ..
make
Then you need to create a file with control points the first column is the x coordinates, the second the y
coordinates. The separation parameter is a single space. Then you can use the CLI by specifying the file name and the
number of points like this,
./spline file.txt 100
./bspline file.txt 100
The script will give (a, x, y, dx, dy) and store the data in the x_output.txt file.
