How plot or view each element of optimexpr variable in case of problem-based optimization?

I have written a code with some variables and one of them is w(optimexpr) which is a combination from two optimvar variables.

v = optimvar('v',length(T),length(geradores),...
    'Type','integer','LowerBound',0,'UpperBound',1);
u = optimvar('u',length(T),length(geradores),...
    'Type','integer','LowerBound',0,'UpperBound',1);

w = optimexpr(length(T),length(geradores));

for j = 1:length(T)
    for k = 1:length(geradores)
        if j==length(T)
            w(j,k) = u(j,k)-u(1,k)+v(j,k);
        else
            w(j,k) = u(j,k)-u(j+1,k)+v(j,k);
        end
    end
end

To show or plot elements of optimvar just write this:

fprintf('\nMatriz v\n\n')
disp(sol.v)

fprintf('\nMatriz u\n\n')
disp(sol.u)

I have tried the same command for use w for plot/display but matlab show me error:

Unrecognized field name "w".

Error in otimizacao_gerenciamento2 (line XXXX)

disp(sol.w)

Someone help me with this, please? Thanks in advance.
