i want the output as probability value but i am only getting a graph. i want to know how can we obtain values from surface viewer of fuzzy logic toolbox of Matlab software?

The graph or output values from the surface viewer on the Fuzzy Logic App are actually defuzzified output values.
fis = mamfis('Name', "Test_FIS");
% Fuzzy Input #1
fis = addInput(fis, [-1 1], 'Name', 'E');
fis = addMF(fis, 'E', 'zmf', [-0.5 0.25], 'Name', 'N');
fis = addMF(fis, 'E', 'gaussmf', [0.25 0], 'Name', 'Z');
fis = addMF(fis, 'E', 'smf', [-0.25 0.5], 'Name', 'P');
% Fuzzy Output
fis = addOutput(fis, [-1 1], 'Name', 'U');
fis = addMF(fis, 'U', 'zmf', [-0.5 0.25], 'Name', 'N');
fis = addMF(fis, 'U', 'gaussmf', [0.25 0], 'Name', 'Z');
fis = addMF(fis, 'U', 'smf', [-0.25 0.5], 'Name', 'P');
% Plot Membership functions
figure(1)
subplot(2,1,1)
plotmf(fis, 'input', 1), grid on, title('Input')
subplot(2,1,2)
plotmf(fis, 'output', 1), grid on, title('Output')
% Fuzzy Rules
rules = [...
"E==N => U=N"; ...
"E==Z => U=Z"; ...
"E==P => U=P"; ...
];
fis = addRule(fis, rules);
% Generate output of Mamdani FIS
figure(2)
opt = gensurfOptions('NumGridPoints', 201);
gensurf(fis, opt), grid on
hold on
input_E = [0.5 -0.5];
output_U = evalfis(fis, input_E)
q = plot(input_E, output_U, 'o', 'MarkerSize', 10);
q.LineWidth = 1.5;
