Any automatic differentiation tool for MATLAB needs to cope with the large number of functions provided by the toolboxes. For many of these functions, derivatives have to be defined. A powerful macro language for the derivative definition, embedded in the source transformation tool ADiMat, is introduced. The macro language consists of a part where the signature of a function is matched and another part specifying the derivative of that function. Several examples illustrate the expressiveness and use of the macro language. A subset of the macro language is available to the user of ADiMat to improve the performance of the generated derivative code by exploiting high-level structure.
