In which cubic spline interpolation method we need to give endpoint tangent value externally?
a) Natural cubic splines
b) Hermit interpolation
c) Cardinal splines
d) Modern cubic splines
Hermit interpolation:
a) Allows local control
b) Does not allows local control
c) Sometimes allows local control
d) None of these
Which is the correct equation for hermit interpolation?
a) π
(π) = π«k(2π3 β 3π2 +1) + π«k+1 (β2π2 + 3π) + πΉπ
k (π3 β2π2 + π) + πΉπ«k+1 (π3 βπ2)
b) π
(π) = π«k(2π3 β 3π2 +1) + π«k+1 (β2π2 + 3π) + πΉπ
k (π2 β2π + π) + πΉπ«k+1 (π3 βπ2)
c) π
(π) = π«k(2π3 β 3π2 +1) + π«k+1 (β2π3 + 3π2) + πΉοΏ½οΏ½k (π3 β2π2 + π) + πΉπ«k+1 (π3 βπ2)
d) π
(π) = π«k(2π3 β 3π2 +1) + π«k+1 (β2π2 + 3π) + πΉπ
k (π2 β2π + π) + πΉπ«k+1 (π2 βπ)
