MaJIC: A Matlab just in time compiler. This paper describes our experience with MaJIC, a just-in-time compiler for MATLAB. In the recent past, several compiler projects claimed large performance improvements when processing MATLAB code. Most of these projects are static compilers suited for batch processing; MaJIC is a just-in-time compiler. The compilation process is transparent to the user. This impacts the modus operandi of the compiler, resulting in a few interesting analysis techniques. Our experiments with MaJIC indicate large speedups when compared to the interpreter, and reasonable performance when compared to static compilers.
