basisSize

Number of basis functions in each dimension.

Discussion

If tensor dimension k has knot vector tau_k and order K_k, then the number of one-dimensional basis functions in that direction is

\[M_k = \mathrm{numel}(\tau_k) - K_k.\]

basisSize stores the row vector [M_1 ... M_d]. The total coefficient count is prod(basisSize).
