matrix

returns the basis splines of order K evaluated at point t, given knot points tKnot.

---

Declaration

 B = matrix( t, tKnot, K, options )

Parameters

• t points at which to evaluate the splines
• tKnot spline knot points
• K spline order (degree S=K-1)
• D (optional) number of spline derivatives to return, max(D)=K-1

Returns

• B [length(t) M D] where M=length(tKnot)-K

Discussion

Returns the basis splines of order K evaluated at point t, given knot points tKnot. If you optionally provide D, then D derivatives will be returned.
