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.

% ====================== 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
|

|
% 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
|
|
