Definition:Spline Function/Uniform

Definition
Let $\closedint a b$ be a closed real interval.

Let $T := \set {a = t_0, t_1, t_2, \ldots, t_{n - 1}, t_n = b}$ form a subdivision of $\closedint a b$.

Let $S: \closedint a b \to \R$ be a spline function on $\closedint a b$ on $T$.

$S$ is a uniform spline $T$ is a normal subdivision.

That is, the knots of $S$ are equally spaced.
