*Re-implement operators using templates and modern C++. Current system evolved before templates and makes extensive use of macros to define interactions between scalar<->scalar, scalar<->matrix, scalar<->float, etc., etc. | |||
**In liboctave, the directory to work on is liboctave/operators | |||
**In libinterp, the directory to work on is libinterp/operators | |||
**In libinterp, there is also xpow.cc, xdiv.cc in libinterp/corefcn | |||

*A profiler for Octave would be a very useful tool. And now we have one! But it really needs a better interface. | * A profiler for Octave would be a very useful tool. And now we have one! But it really needs a better interface. | ||
*Having {{Codeline|parfor}} functioning would speed code development and execution now that multicore architectures are widespread. See [http://octave.1599824.n4.nabble.com/Parfor-td4630575.html here] and [http://stackoverflow.com/questions/24970519/how-to-use-parallel-for-loop-in-octave-or-scilab here]. Existing code from the [[Parallel package | parallel]] and [http://octave.sourceforge.net/mpi/index.html mpi] packages could perhaps be adapted for this. | * Having {{Codeline|parfor}} functioning would speed code development and execution now that multicore architectures are widespread.

* Develop a performance benchmark for Octave (interpreter, load/save, plotting, etc., but not simply tests of underlying libraries such as BLAS or LAPACK). This benchmark could be run periodically to make sure that changes during development do not introduce regressions in performance. | |||
