IBsplines {cubicBsplines} | R Documentation |
Computation of the integral of a cubic B-spline basis over (t0,x) for a given vector of knots
IBsplines(t0, x, knots)
t0 |
scalar giving lower value of the integration interval. |
x |
vector giving the upper values of the integration interval. |
knots |
vector of knots spanning the desired B-spline basis. |
A matrix of dimension length(x)
by (length(knots)+2)
.
Each integrated cubic B-spline is within a given column.
