Numerical Methods Library for OCTAVE

1 How to install and use NMLibforOctaveIn this part we explain how to install and to use the NMLibforOctave :1.1 On WindowsOnce the installation of Octave (3.0.0 and upper version) is finished you have to add a new pathcorresponding to the NMLibforOctave directory :• Place the directory NMLibforOctave on the installation directory ∼/Octave/ .• Open ∼ /.octaverc .• Add the line : ’addpath("∼/Octave/NMLibforOctave");’.If there is a space ’ ’ in a name of a subdirectory, add the character ’\’ before.Example : "C:/Program Files/Octave/NMLibforOctave"→ addpath("C:/Program\ Files/Octave/NMLibforOctave");• Save and exit.1.2 On LinuxOnce the installation of Octave (3.0.0 and upper version) is finished you have to add a new pathcorresponding to the NMLibforOctave directory :• You can place the directory NMLibforOctave on the installation directory.For example on Ubuntu after installing octave with your package manager (package name: octave 3.0) copy NMLibforOctave in /usr/share/octave/3.0.0/m’).• Open ∼ /.octaverc .• Add the line : ’addpath("∼/NMLibforOctave");’.• Save and exit.2 About the NMLibforOctave’s contentThe library NMLibforOctave’s content can be decomposed is different application fields :1.
