Compute Lp distance between two 2D functional data objects (surfaces)

For 2D functional data, the Lp distance is computed as: d(f, g) = (∫∫ |f(s,t) - g(s,t)|^p ds dt)^(1/p)

Usage

metric_lp_2d(fdata1, fdata2, argvals_s, argvals_t, p, w)

Details

Data is stored as flattened matrices: n x (m1 * m2) where m1 = len(argvals_s), m2 = len(argvals_t) Data is stored in row-major order for the surface: f(s_i, t_j) is at index i * m2 + j
