Details:

function [theta, J_history] = gradientDescent(X, y, theta, alpha, num_iters)

  m = length(y); % number of training examples
  J_history = zeros(num_iters, 1);

  for iter = 1:num_iters


    theta = theta - alpha/m * sum (  (((X*theta) - y) )*X  ) 
 
    J_history(iter) = computeCost(X, y, theta);

  end

end




...................... 

above code nets this error ( with an incorrect column number )

......................

error: operator *: nonconformant arguments (op1 is 97x1, op2 is 97x2)
error: evaluating argument list element number 1
error: evaluating argument list element number 1
