J = (1 / m) * sum(-y'*log(sigmoid(X * theta)) - (1-y)'*log( 1 - sigmoid(X * theta))) + (lambda/(2*m)) * sum(theta(2:length(theta)).*theta(2:length(theta))) ;
grad = (1 / m) * sum( X .* (sigmoid(X*theta) - y) ); grad (:,2:length(grad)) = grad(:,2:length(grad)) + (lambda/m)*theta(2:length(theta))';
% =============================================================
grad = grad(:) ;
end

Why would you use end here? It is reserved to close a switch block, if, for, while, classdef or function.
