jacw {bspline} | R Documentation |
Knot Jacobian of B-spline with weights
Description
Knot Jacobian of B-spline with weights
Usage
jacw(jac, qws)
Arguments
jac |
Numeric array, such as returned by |
qws |
Numeric matrix, each column is a set of weights forming a B-spline. If qws is a vector, it is coerced to 1-column matrix. |
Value
Numeric array of size nx x ncol(qw) x nk
, where nx=dim(jac)[1]
and nk is the number of knots dim(jac)[3]+n+1
(n being polynomial order).
