Octave[edit]

GNU Octave is a high-level programming language, primarily intended for numerical computations. Octave helps to solve linear and nonlinear problems numerically, and to perform other numerical experiments using a language that is mostly compatible with MATLAB.^[1]

-== Preparation ==
+{{MerlinMultipageExperienceSubpages
-In this exercise, you'll be generating graphic files by using Octave.  In order to view these files, you'll save them in a special directory called "~www" which must be created in your home directory.  The following instructions will instruct you on how to create this directory.

-{{Prepare WWW Directory}}
+}}
-== Graphing ==
-Octave may be started by typing 'octave' in the shell.  It's easiest to perform this in your '''www''' directory so the files that you create will be saved there.
-{{ConsoleLine|liang-xue@codermerlin:~$|cd ~/www}}
-{{ConsoleLine|liang-xue@codermerlin:~$|octave}}
-You'll know you're in Octave when you see the Octave prompt.
-{{ConsoleLine|octave:1>|}}
-In order to enable graphics plotting, execute the following command:
-{{ConsoleLine|octave:1>|graphics_toolkit("gnuplot")}}
-We'll begin with a 3-D example to demonstrate the power of Octave and the ease with which complex graphs can be created.
-== Examples ==
-=== 3-D Sombrero Plot ===
-{{ConsoleLine|octave:2>|tx {{Equal}} ty {{Equal}} linspace (-8, 8, 41)';}}
-{{ConsoleLine|octave:3>|[xx, yy] {{Equal}} meshgrid (tx, ty);}}
-{{ConsoleLine|octave:4>|r {{Equal}} sqrt (xx .^ 2 + yy .^ 2) + eps;}}
-{{ConsoleLine|octave:5>|tz {{Equal}} sin (r) ./ r;}}
-{{ConsoleLine|octave:6>|mesh (tx, ty, tz);}}
-{{ConsoleLine|octave:7>|xlabel ("tx");}}
-{{ConsoleLine|octave:8>|ylabel ("ty");}}
-{{ConsoleLine|octave:9>|zlabel ("tz");}}
-{{ConsoleLine|octave:10>|title ("3-D Sombrero plot");}}
-We can now print the plot to a file with:
-{{ConsoleLine|octave:11>|print -dpng sombrero.png}}
-It may take a few seconds to produce the file; be patient.  When the prompt returns, the file may be viewed in a browser.
