CasADi in C++: How do I set the numerical values of MX symbols?

[YZ He]

Hello all,

In Python I managed to access and modify the numerical value of MX symbols like:

self.opt_p = struct_symMX(...)

self.opti_vars = struct_symMX(...)

self.opti_vars_num = self.opti_vars(0)

self.opt_p_num = self.opt_p(0)

...

# modify the values in opt_p

self.opt_p_num['u_ini'] = vertsplit(u_ini)

self.opt_p_num['y_ini'] = vertsplit(y_ini)

self.opt_p_num['ref'] = vertsplit(r)

What is the equivalent way of doing so in C++? Thanks!
