function J = computeCost(X, y, theta)

%COMPUTECOST Compute cost for linear regression % J = COMPUTECOST(X, y, theta) computes the cost of using theta as the % parameter for linear regression to fit the data points in X and y

% Initialize some useful values m = length(y); % number of training examples

% You need to return the following variables correctly J = 0;

% ====================== YOUR CODE HERE ====================== % Instructions: Compute the cost of a particular choice of theta % You should set J to the cost.

J = (1/(2*m))pow((sum((thetaX)')' - y),2)
