I want to solve optimization problem but when run it notifide : Undefined function or variable optimvar, how to fix it ?

clear; clc

X = optimvar('x','LowerBound',0,'UpperBound',inf);

Y = optimvar('Y','LowerBound',0,'UpperBound',inf);

linprob = optimproblem('Objective',X+Y);

linprob.Constraints.cons1 = 2*X+2*Y >= 4;

linprob.Constraints.cons2 = -2*X+4*Y >= -2;

linprob.Constraints.cons3 = -2*X+Y >= -8;

linprob.Constraints.cons4 =-2*X+Y <= -2;

linprob.Constraints.cons5 = Y <= 6;

linsol = solve(linprob);

You need to install the Optimization toolbox
