Source Transformation for the Optimized Utilization of the Matlab Runtime System for Automatic Differentiation.
3rd International Workshop on Computational Engineering. Stuttgart, Germany (October 6-10, 2014)
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
The ADiMat software is a tool that offers automatic differentiation of Matlab functions using a hybrid approach that combines source transformation and operator overloading. Performance tests showed a weakness with a derivative class of ADiMat. In a first step, the Matlab runtime environment is tested regarding function and method call overheads as well as property access overhead with Matlabs objects. An automatic method, transforming the XML based abstract syntax tree created with ADiMats toolchain through a set of stylesheets, was developed. The process completely removes the derivative object usage from any derivative function created with ADiMat. As a result, performance is improved considerable depending on the data container storing the derivative directions.
