OctaveWeb

To run an Octaveweb example
Simply click on the radio button corresponding to the example you want to see (check out the code links, too), and hit the submit button.
To run Octaveweb using your own commands
type the octave code you want to execute into the text window and then click on the submit button. A new html page is produced, with the text output of your code followed by the graphical output (if any) from your code (the short code snippet that occupies the text window at start-up is an example, in case you don't know octave already).

an 'SQO' model
Eigenvalues: calves, yearlings
SVD

Applications:
Abe Lincoln (as you've never seen him) -- the SVD and "fleshing out" a matrix

A non-linear regression example (bodies in rigor mortis)
ODE solver

Other:
random data, solving, rref
Muller's method (root-finding)
