You can plot predicted probabilities from a logisitc regression model:
y = randi([0, 1], 1000, 1);
x = randn(1000, 1);
mdl = fitglm(x, y, 'Distribution', 'binomial', 'Link', 'logit');
xNew = randn(1000, 1);
yNew = mdl.predict(xNew);
plot(xNew, yNew, '.', 'MarkerSize', 4)
Similarly, you can apply predict to other models (SVM etc) to get the predicted response.
