I-spline

I-splines, or interpolating splines, are a type of spline function used in numerical analysis and computational mathematics for interpolation tasks. They are particularly notable for their ability to provide a smooth curve passing through a given set of data points or knots. ### Characteristics of I-splines: 1. **Interpolation**: I-splines are designed to interpolate a set of points. They ensure that the curve passes exactly through the specified data points.
