Can someone help me with the following Question?
I am not sure if B-spline/NURBS can express as basic function in matrix, as,
$$ x(t) = B(t)c $$ $$ B(t) = [b_1(t) ... b_M(t)] $$ in which x(t) is a Dx1 states, B(t) is known temporal B-spline basis functions, each individual basis function is alos D-dimensional, c is a Mx1 column of coefficients.
If yes, What's the detailed expression of B(t)?
Thank you in advance.
