The term "B-spline" was coined by Isaac Jacob Schoenberg and is short for basis spline. A spline function of order is a piecewise polynomial function of degree in a variable . The places where the pieces meet are known as knots. The key property of spline functions is that they and their derivatives may be continuous, depending on the multiplicities of the knots.
