Hi,
I need to update and share a variable between two functions to solve a system of ODEs. These functions are, respectively, odefun - the function that ode45 accepts as input - and myOutputFcn - that is the custom output function that ode45 accepts as option.
function dsol_dt = odefun(t, sol, hyspar, L, M)
dsol_dt = zeros(2,1);
u = sol(1,1);
y = sol(2,1);
fri = hyspar.fri;
ud = y;
yd = - L(y,fri) / M ;
dsol_dt = [ud; yd];
end
function status = myOutputFcn(t,sol,flag,hyspar)
switch flag
case 'init'
case ''
hyspar.fri = RestoringForce(sol(1),sol(2),ecc,hyspar);
case 'done'
assignin('base','hyspar.fri',fri);
end
status = 0;
end
I would share and update the variable that is hyspar.fri (fri). When it updates in myOutputFcn through the function RestoringForce, I am only changing the local copy. So, in odefun will not be taken the updated value of the variable fri.
I read the main techniques to share variables between workspaces
but I didn't find any examples that suit me, I guess...
I would like to specify that I can't call RestoringForce in odefun for several different reasons.
Kind regards
