BasisFunctions v0.7.0

Diff since v0.6.5

Breaking changes

an expansion (dictionary+coefficients) no longer acts as the vector of coefficients. This means it cannot be indexed (as in e[2] returning the second coefficient) and cannot be iterated over
there are some interface cleanups. The norm and moment functions with a combination of dictionary and coefficient as arguments are renamed to dict_norm and dict_moment instead. One can still invoke norm on a basisfunction, e.g., norm(dict[3])

Features

computing with expansions has improved. For example, computing the diagonal of the Christoffel-Darboux kernel of a polynomial basis can be done as follows:

julia> basis = orthogonalize(Legendre(3))
DiagonalOperator(v) * Legendre(3)

v = 3-element Vector{Float64}:
 0.707107
 1.22474
 1.58114

julia> k = sum(phi^2 for phi in basis)
Expansion(Legendre(5), v)

v = 5-element Vector{Float64}:
 1.5
 8.28036e-16
 1.71429
 1.14325e-15
 1.28571

Diff since v0.6.4

supporting routines for the Plots package have been moved to an extension conditional on loading RecipesBase
similarly, support for PGFPlotsX has moved to an extension
