ejemplo de código de matriz aleatoria de números enteros

Ejemplo 1: matriz aleatoria numpy

>>> np.random.rand(3,2)
array([[ 0.14022471,  0.96360618],  
       [ 0.37601032,  0.25528411],  
       [ 0.49313049,  0.94909878]]) 

>>> np.random.random_integers(low=0, high=9, size=(3,2))
array([[2, 3],
       [2, 3],
       [6, 3]])

Ejemplo 2: int aleatorio numpy

np.random.randint(2, size=10) # Creates binary sample of size 10
np.random.randint(5, size=10) # Creates sample with 0-4 as values of size 10

np.random.randint(5, size=(2, 4))

Ejemplo 3: generar python de matriz entera aleatoria

import numpy as np

randi_arr = np.random.randint(start, end, dimensions)
#random integers will be sampled from [start, end) (end not inclusive)
#end is optional; if end is not specified, random integers will be sampled from [0, start) (start not inclusive)
#dimensions can be specified as shown here; (m,n) #2D array with size 'm x n'
