Details:
I found a strange behavior using function handles in Octave.
Here is what I'm trying to do:
1) Create a function handle in a structure like:
model.odefun = @plant_ODE
2) Save the handle
save stored_model.mat model
3) when I try to call the function:
load stored_model.mat;
model.odefun(0,[2 4]);
octave does not recognize "model.odefun" as an handle anymore.
Actually the problem is a little bit more complex. Attached is a small
example. It works in Matlab but it doesnt in Octave.
clear all
close all
clc
model = create_func;
model.odefun([2 3],0)
save -binary handle_saved.dat model
clear all
load handle_saved.dat
model.odefun([2 3],0)
function [model] = create_func
model.odefun = @gas_phase_ODE;
end
function dxdt = gas_phase_ODE(x,t)
k_ = 0.16;
v = [-2 1];
r = k_*x(1)^2;
dxdt = v'*r;
end
