Tips and Tricks
Get file info when generate_html fails or warns
Since generate_html gives errors about the random files generated, it is useless when debugging help text. The following command shows the first few lineas of the files created by generate_html.
f_old=/tmp/$(ls -1 -t /tmp | head -1);while true; do f=/tmp/$(ls -1 -t /tmp | head -1); if [ "$f" != "$f_old" ]; then echo $f; grep '@deftypefn ' --include="*octave-help*" $f; f_old=$f; fi; done
run this in a different terminal before using generate_html is not ideal,but it does the trick
Some options to pass to make when compiling from source
DOC_TARGETS=avoids building the PDF but still builds function helps.
--disable-atomic-refcountimproves performance when building CLI only.
Getting help from CLI
- know the function -->
- Know what to do but not the function name -->
- 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.
test syntax highlight
|Code: Loading the file as polygon compatible with geometry package|
function y = deserializeInt (data) y = bitpack ( cell2mat( arrayfun( @(x)bitget(x,1:8), data, "UniformOutput", false ) )', "uint16"); y = double (y); endfunction
- Extend tutorial Geometry package
Non-negative matrix factorization
- 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.✔
- Create repository to keep scripts to package it for OF. ✔
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).
