[Octave-bug-tracker] [bug #56393] missing deval function for ode

[Carlo de Falco]

Follow-up Comment #2, bug #56393 (project octave):

@JPi I don't see any incompatibility just the function deval is missing I
think the group is correct.

BTW as pointed out on the mailing list, the use of deval can
be avoided with the following code:


 y0=[1;1];
 T=40;
 t=[0:0.1:T];%%  you choose times t(k)  where solution is evaluated
 [~, y] = ode45(@(t,y) [y(2);-y(1)], t, y0);
 plot (t, y(1,:), 'xr', t, cos(t)+sin(t),'-b')


that works with both matlab and octave
