function plotData(X, y) %PLOTDATA Plots the data points X and y into a new figure % PLOTDATA(x,y) plots the data points with + for the positive examples % and o for the negative examples. X is assumed to be a Mx2 matrix. % % Note: This was slightly modified such that it expects y = 1 or y = 0 % Find Indices of Positive and Negative Examples pos = find(y == 1); neg = find(y == 0); % Plot Examples plot(X(pos, 1), X(pos, 2), 'k+','LineWidth', 1, 'MarkerSize', 7) hold on; plot(X(neg, 1), X(neg, 2), 'ko', 'MarkerFaceColor', 'y', 'MarkerSize', 7) hold off; end
