//! Linear maps between function bases.
//!
//! A quantity f(x) = Σ_j f_j B_j(x) is described by coefficients in a [`Space`] of
//! [`Element`]s. rebasis computes the sparse matrices that take f_j to coefficients or
//! measurements in another space: instrument line shapes ([`measure`]), point evaluation
//! ([`evaluate`]), L2 projection for regridding ([`Projection`]) and penalized least-squares
//! fitting for smooth conservative upsampling and smoothing ([`Fit`]).
//!
//! All inner products are exact for piecewise-polynomial elements (boxes, hats, B-splines,
//! tabulated shapes) and accurate to rounding for the analytic profiles ([`Profile`]).

// Index loops read most clearly in the banded and sparse kernels.
