Integrated minimal symbolic differentiation from SymDiff.jl by Jukka Aho:
- differentiate(): Symbolic derivatives for polynomials (+, -, *, /, ^)
- simplify(): Expression simplification with numeric evaluation
- Zero external dependencies for basis function generation!
Changes:
- src/basis/create_basis.jl: Added differentiate() and simplify()
- src/basis/subs.jl: Added local simplify with numeric evaluation
- src/basis/abstract.jl: Removed Calculus import
This replaces the Calculus.jl dependency with ~100 lines of pure Julia
code specifically designed for polynomial basis functions.
