Programming with Octave

• A very similar programming language to Matlab. In most cases you should be able to port the code right over…
• However, “plot-ing” does not work very well for me on OS X or XP. Looks like I'll need to still develop in matlab.

• Some stolen from Steel and Silicon

fflush(stdout) //Clears out the buffer as Octave doesn't print them out right away.

• STARTING TUTORIAL

mkoctfile --mex peakdet.c

• Running into some problems…fix is on this thread

//Need to use some form of these flags
sudo gem install octave-ruby -- --with-octave-include=/usr/include/octave-3.2.0/octave
--with-octave-lib=/usr/lib/octave-3.2.0/lib

• It appears that octave-ruby is choking on the new version of octave (3.2.X), as this thread got the errors I was getting. I'm not sure what the best thing to do is, but I'm going to try deprecating octave and seeing if the connection works.

• 6/21: Just run the below operations

> sudo apt-get install octave octave-headers
> octave
octave> mkoctfile --mex mexfile.c

• (6/16) Ran into a good bit of problems getting Octave to use MEX files on the Mac. (something about not finding lgfortranbegin). The author suggested using a different dmg on this thread, but then I got a bunch of complaints about 32-bit and 64-bit. Aaaargh.
  • Switching to just trying to get everything working on Ubuntu/Linux, since that's what we'll be using in the end for the server.

• Shamelessly copied and updated from Octave Wiki
• Step 5 (different source location):

wget http://prdownloads.sourceforge.net/hpc/gfortran-snwleo-intel-bin.tar.gz?download
tar -xzf gfortran-snwleo-intel-bin.tar.gz
sudo cp -r ./usr/local/* /usr/local

• Step 6: sed

wget ftp://ftp.gnu.org/gnu/sed/sed-4.2.1.tar.gz
tar -xzf sed-4.2.1.tar.gz
cd sed-4.2.1
./configure --prefix=/usr/local --with-included-regex --with-included-gettext
make && sudo make install
sudo mv /usr/bin/sed /usr/bin/__sed

• Step 7: gawk

wget http://ftp.gnu.org/pub/gnu/gawk/gawk-3.1.8.tar.gz
tar -xzf gawk-3.1.8.tar.gz
cd gawk-3.1.8
./configure --disable-nls --prefix=/usr/local
make && sudo make install

• Step 8: readline

wget http://ftp.gnu.org/pub/gnu/readline/readline-6.2.tar.gz
tar -xzf readline-6.2.tar.gz
cd readline-6.2
./configure --prefix=/usr/local --enable-shared
make && sudo make install

• Step 9: gnuplot

wget http://sourceforge.net/projects/gnuplot/files/gnuplot/4.4.3/gnuplot-4.4.3.tar.gz/download
tar -xzf gnuplot-4.4.3.tar.gz
cd gnuplot-4.4.3
./configure --prefix=/usr/local
make && sudo make install

• Step 10: octave

wget ftp://ftp.gnu.org/gnu/octave/octave-3.4.1.tar.gz
tar -xzf octave-3.4.1.tar.gz
cd octave-3.4.1
./configure --prefix=/usr/local --enable-shared --disable-readline
make && make check && sudo make install
