a few tips, in case you are not familiar with the built-in docs.

at the octave prompt enter "doc". you can then use the arrow keys to
go up and down and select from the bullet-points "*" using enter. when
you have finished hit q to quit.

to go straight to the part you want "doc Nonlinear" works in your case.
