Tasmanian.jl

Wrapping the awesome tasmanian library.

Example 1: The Darth Vader Function

Approximating the function at increasing levels of grid refinement at 1000 randomly chosen points.

Example 2: Genz test function

This approximates f(x,y) = 1.0 / (abs(0.5 - x^4 - y^4) + 0.1).

Checklist

• Basis functionality wrapped: getters, setters
• Simple tests implemented
• LocalPolynomialGrid implemented
• grid refinement implemented
• Automate build of library via BinaryBuilder
• More tests
• Documentation
• Other grid types missing: global, sequential and wavelet

Installation

To install julia package

Pkg.clone("[email protected]:floswald/Tasmanian.jl.git")
Pkg.build("Tasmanian")

The Tasmanian library will be downloaded as a precompiled binary version fitting to your system.
