WebJust like Hassan's answer and Fred Foo's answer, my answer has time complexity O(ϴRI). Their answers have space complexity O(ϴR+RI) (I am not actually sure about this), while mine unfortunately has space complexity O(ϴRI) - this is because numpy can multiply a ϴ×R matrix by a R×I matrix without allocating an additional array of size ϴ×R×I. WebYou can rely on broadcasting instead of dot: a[:,None]*b . Or you can simply use outer: np.outer(a,b) All three options return the same result. You might also be interested in something like this so that each vector is always a 2D array: np.dot(np.atleast_2d(a).T, np.atleast_2d(b)) dr ramanan oncologist
