Expand description
Constant (intercept) basis function.
Provides the trivial single-function basis whose only member is the
constant function f(t) = 1. Its evaluation on a grid t is a
column-major m × 1 matrix of ones — the intercept column of a
regression design matrix. This mirrors R’s create.constant.basis
(fda) and fdata.usc’s constant basis.
Functions§
- constant_
basis - Evaluate the constant basis on a grid of evaluation points.
