Plugin 'ipopt' is not found - MATLAB

[Quoc Phong Pham]

Hi everyone!
I just have downloaded CasADi for Matlab from the official website: https://web.casadi.org/get/ 

I want to use 'ipopt' solver but Matlab says that Plugin 'ipopt' is not found. 

Who have met this problem? Please help me to fix that!

Thanks!

CODE:

import casadi.*
x = SX.sym('x');
y = SX.sym('y');
v = [x;y];
f = unc_rosenbrock_fun(x,y);
g = [];

nlp = struct('x', v, 'f', f', 'g', g);

solver = nlpsol('solver', 'ipopt', nlp);

ERROR:

CasADi -  WARNING(".../casadi/core/plugin_interface.hpp:322: Assertion "handle!=nullptr" failed:

I got it guys. You have to extract CasADi to C disk and save this path to Matlab. Then it will work.
