How To Create A Random Matrix?

I want create a random matrix like [[[100, 50, 25], [22, 75, 195]]] My code is n = 1 r = 2 e = 3 sup = [] for i in range(n): sup1 = [] for c in range(r): sup0 =

Solution 1:

This should work (No idea what e does):

sup = [[random.randint(0, 200) for _ in range(r)] for _ in range(n)]

Solution 2:

You can use numpy to directly get the random matrix of desired size with values in a given range.

>>> numpy.random.randint(low = 0, high = 200, size=(2, 4))
array([[ 75,  21, 132,  90],
       [112,  11, 104, 114]])

>>> r = 2
>>> n = 1
>>> numpy.random.randint(low = 0, high = 200, size=(r, n))
array([[94],
       [51]])
