getting help
- know the function -->
help function_nameorhelp function_name. - Know what to do but not the function name -->
lookfor what_to_do. - Can't remember the fullname of a function (or have a guess) --> partial_name_of_function then press <TAB-key> twice
- Did it once but can't remeber --> <Ctrl>+<R> to search the history.
TODO list
- Write description of packages Geometry package,Mechanics package,Robotics package.
- Start the API for RSB.

make output format a valid input format
An output format that prints valid input commands, so one can copy and re-execute the code. From IRC
(04:57:05 PM) jwe: It might not be too hard to implement what you want. There is a flag in the pr-output functions for pr_as_read_format and many (but probably not all) of the types that are printed there do something with that. And it is not hooked in to the format function, so you can't enable it.
(04:57:31 PM) jwe: pr-output.cc and pr_as_read_syntax
extend sub2ind and ind2sub
We are extending sub2ind and ind2sub to work with triangular matrices. Currently private functions of mechanics. A string argument triggers the behavior. The string argument can be "triu" or "tril". After this str argument we accept an extra scalar value indicating that the triangular matrix is off diagonal (as in tril and triu). So, the first modification to the C++ code will be
- Check if any of the argument is a str.
- Check what kind of triangular matrix (up or low).
- If the argument after the str argument is a scalar, it indicates off diagonal triangular matrix (we do not have algo for that yet, though).

- Add nmf_bpas and nmf-pg to linear-algebra ✔
- Get nmf_toolbox from DTU under free license. ✔
- Add it to linear-algebra and create nnmf.m compatible with MATLAB calling all the methods.

- Asked for a GPLv3 version of GPML. They answer but license is FreeBSD. A new version is comming out in June 2012, so I will wait to start the port.

Porting the package. May be good to port SC as well
