Quiver example

[Johannes Wolfgang Woger]

Does anyone out there have a simple octave program that uses the quiver 
function for graphics? I need an example.

Thanks!

Try

function dx = EXP_DGL(x,t)
dx = x;
end

################# Plot anzeigen
t = [0:0.1:10];
x = lsode('EXP_DGL',0.1,t);
plot(t,x)
################# Richtungsfeld anzeigen
x = 0:0.5:5;
t = 0:0.25:5;
for k=1:length(x)
for l = 1:length(t)
DX(k,l) = EXP_DGL(x(k),t(l));
DT(k,l) = 1;
end;
end;
quiver(t,x,DT,DX);
