hi!
first of all, it's great there's a free alternative to matlab and such.
secondly, I'm a big idiot. how to make a direction field plot of a simple
differential equation? I found the following recipe for matlab:
dx = 0.1;
[xp,yp] = meshgrid ( 0:dx:2, -1:dx:1 );
u = dx * ones ( size ( xp ) );
v = dx * stiff_ode ( xp, yp );
quiver ( xp, yp, u, v )
but it doesn't seem like quiver() is supported by octave.. I'm sorry, I just
found out about Octave a few minutes ago, and I'm being way too impatient.
thanks for any help!!
