WebNow, a vector can be viewed as one column or one row of a matrix. But in numpy, there is a difference between an array with shape (5,) and an array with shape (5,1). Is there a mathematical equivalent to the numpy distinction between shape (5,) and shape (5,1), or are we to view both as vectors?
