Problem with the "lineprog" function

Hello, can someone help me? i´m doing a transportation problem where I have to minimaize the cost, but at the end when I run it, it show me:

'linprog' requires Optimization Toolbox.
Error in try1 (line 19)
[xopt, fval] = linprog(lpp.f,lpp.A,lpp.b,[],[],lpp.lb);

Do someone know what to do?

I´m using the R202b version

Than you.
