boundary(s; direction=1, component=1)
∂(s; direction=1, component=1)

Return boundary component in direction of the object s.

replace_ref_begin_end!(ex)

Recursively replace occurrences of the symbols :begin and :end in a "ref" expression (i.e. A[...]) ex with the appropriate function calls (firstindex or lastindex). Replacement uses the closest enclosing ref, so A[B[end]] should transform to A[B[lastindex(B)]]

nullspace(A::AbstractMatrix{T<:Real})

Construct a left basis for the null space of matrix A.

nullspace(a::AbstractVector{T}) where {T<:Real}

Find a sparse basis for the null space of a vector. The entries are computed such that null space operator is maximally sparse and column sum of absolute values equals 1.0 for improved conditioning.

AbstractMapping{Dim,S1,S2}

Abstract type representing a mapping with an Dim dimensional domain, taking values in an S1 x S2 codimensional space.

AbstractSpline{Dim} <: ScalarMapping{Dim}

Abstract subtype of ScalarMapping that represents a AbstractSpline function.

Boundary{S<:AbstractMapping}

Iterator over the boundary components of a mapping of type S.

Degree

Polynomial degree (typeallias of Integer).

Dimension

Dimension (typeallias of Integer).

Regularity

Regularity of the B-spline basis (typeallias of Integer).

ScalarMapping{Dim} <: AbstractMapping{Dim,1,1}

Abstract subtype of AbstractMapping` that represents scalar-valued mappings.
