matlab randint,Matlab的randint函数用法「建议收藏」

RANDINT Generate matrix of uniformly distributed random integers. OUT = RANDINT generates a “0” or “1” with equal probability. OUT = RANDINT(M,N) generates an M-by-N matrix of random binary numbers. “0” and “1” occur with equal OUT = RANDINT(M,N,IRANGE) generates an M-by-N matrix of random integers. Examples: out = randint(2,3) out = randint(2,3,4) out =

    python random.randint函数用法(random.randint()是什么意思)

    numpy.random.randint(low, high=None, size=None, dtype=’l’) 函数的作用是,返回一个随机整型数,范围从低(包括)到高(不包括),即[low, high 如int64、int等等 输出:out: int or ndarray of ints 返回一个随机数或随机数数组 例子: >>> np.random.randint(2, size=10) array ([1, 0, 0, 0, 1, 1, 0, 0, 1, 0]) >>> np.random.randint(1, size=10) array([0, 0, 0, 0, 0, 0, 0, 0, 0, 0]) >>> np.random.randint(5, size=(2, 4)) array([[4, 0, 2, 1], [3, 2, 2, 0]]) >>>np.random.randint(2,
