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. % Create New Figure figure; hold on; % ====================== YOUR CODE HERE ====================== % Instructions: Plot the positive and negative examples on a % 2D plot, using the option 'k+' for the positive % examples and 'ko' for the negative examples. % % Seperate between positive and negative ( 0 or 1 admission) to later represent on graph pos = find(y == 1); neg = find(y == 0); % Setup Plots note: X(pos,1) finds all rows with positive output thanks to % our find function returning a vector containing the indeces of each plot(X(pos,1), X(pos,2), 'k+', 'LineWidth', 2, 'MarkerSize', 7); plot(X(neg,1), X(neg,2), 'ko', 'MarkerFaceColor', 'y', 'MarkerSize', 7); % ========================================================================= hold off; end
