clamped)\n- [x] Chebyshev\n- [x] arbitrary order polynomials (Neville's method)\n- [x] polynomial coefficients (efficient Vandermonde solver)\n- [x] end-point cubic Hermite\n\n##### Two Dimensions, Regular Grid\n\n- [x] linear\n- [x] piecewise cubic\n- [x] Chebyshev\n\n##### N-Dimensions, Scattered Points\n\n- [x] radial basis functions (any choice of function)\n- [x] Shepard\n\n-----\n\n### Basic Usage\n\nSee the [**tutorial**](https://markmbaum.github.io/BasicInterpolators.jl/dev/tutorial/) for more complete examples.\n\n```julia\nusing BasicInterpolators, ForwardDiff\n\n#some data to interpolate\nx = [-1, 0.5, 2, 3]\ny = [1, 3, -0.5, 0]\n\n#a linear interpolation struct\np = LinearInterpolator(x, y)\n\n#interpolate at one point\np(2.5)\n\n#interpolate at lots of points\np.(LinRange(-1, 3, 100))\n\n#compute the derivative dy/dx\nForwardDiff.derivative(p, 1.0)\n\n#make an interpolator that doesn't check boundaries (allows extrapolation)\np = LinearInterpolator(x, y, NoBoundaries())\n```\n\n-----\n\n### Other packages\n\nSome notable packages with other/advanced methods:\n\n1.
