I tried to run a Matlab code with Octave and it returned with following error message.
error: 'rate_eq' undefined near line 10 column 25
error: called from
laser_rate_equation>@<anonymous> at line 10 column 25
starting_stepsize at line 46 column 5
ode45 at line 192 column 25
laser_rate_equation at line 10 column 10
It seems Octave doesn't accept this command [T,Y]= ode45(@(t,y) rate_eq(t,y,V),tspan,y0); this is exactly the same way to call function with both Matlab and Octave.
How do I fix the problem?
ps; The function rate_eq is
function dy= rate_eq(t,y,V)
dy = zeros(3,1);
I = 0.3;
te = 2.2E-9;
tp = 1.6E-12;
BuyukGama = 0.3;
a = 2.5E-20;
e = 1.602E-19;
n0 = 1E24;
h = 6.626074E-34;
dy(1) = (I/e) - y(1)/te - (BuyukGama*c*a*(y(1)/V-n0)/ug)*y(2);
dy(2) = (BuyukGama*c*a*(y(1)/V-n0)/ug)*y(2)- y(2)/tp + Betasp*B*y(1)^2/V ;
dy(3) = h*nuu*vg*am*dy(2)/2;
