(np.matrix) • In my experience, because arrays operate on matrix rules, it usually doesn’t make a difference whether you use np.array to make a matrix structure or np.matrix. • Other useful linear algebra commands: np.dot, np.cross, np.linalg.inv (take the inverse), np.transpose, np.diag, np.eye (for …
3 ways to initialize a Python Array - AskPython
array). There are several ways to initialize an ndarray. One can start with a list and cast it as an ndarray. list1 = [[0,1,2,3,4], [5,6,7,8,9], [10,11,12,13,14]] arr1 = np.array(list) One can also specify a range of values and then reshape the single-dimensional array into a two (or more) dimensional array. arr2 = np.arange(15).reshape(3,5)
