Apache Commons Nabla

Compare

Claimed by Apache Software Foundation Analyzed about 19 hours ago

Nabla is an algorithmic differentiator for mathematical functions. Just like the mathematical Nabla operator transforms a function into its differential, the Nabla library transforms an existing java object implementing a function double f(double) { ... } into another java object that in ... [More] addition to computing the value of f like the original one also computes its derivative. The created object is built by applying the classical exact differentiation rules to the function underlying expressions. There are no approximations and no step sizes. Nabla uses bytecode transformation to create the differentiated class and instances [Less]

FFC

Compare

  Analyzed about 14 hours ago

FFC works as a compiler for multilinear forms by generating code (C or C++) for the evaluation of a multilinear form given in mathematical notation. This new approach to form evaluation makes it possible to combine generality with efficiency; the form can be given in mathematical notation and the ... [More] generated code is as efficient as hand-optimized code. FFC is a component of the FEniCS project, see http://www.fenicsproject.org. [Less]
