Basis function matrices #312

Closed jzwar closed 11 months ago

jzwar commented 11 months ago

This has been implemented many times in different spots, Leading to redundant code.

Overview

Create basis function matrices directly using either scipy or numpy depending on availability.

Addressed issues

Showcase

spline = some_spline()

matrix = splinepy.utils.data.make_matrix(
  *spline.basis_function_matrix(queries),
  spline.cps.shape[0]
)
assert np.allclose(matrix @ spline.cps, spline.evaluate(queries))
