This implements single algebra and evaluation on simple univariate functions. There are a few ways in which it can be used.
- UnivariateFunctions can be used in the creation of splines. This has the added advantage that a spline implemented as a UnivariateFunction can be manipulated easily. It can be differentiated and then added to another function, etc.
- Any continuous interpolation scheme can be done with the added benefit that derivatives/integrals/products etc can be found analytically.
- Basic approximation schemes like OLS regression and chebyshev polynomials can be done with the added benefit that derivatives/integrals/products etc can be found analytically.
This is faster and simpler than the closely related package MultivariateFunctions.jl. The cost is that it is restricted to only one dimension.
