1. 相同点在0~1均匀分布中产生随机数(包含0，不包含1）使用numpy.random.random((2,100))、numpy.random.rand(2,100)和numpy.random.randn(2,100)均可产生2行100列数组2. 不同点random.random()参数为元祖，random.randn()输出数组符合正态分布...

1. 引用numpy.dot()函数解释numpy.dot(a, b, out=None)Dot product of two arrays. Specifically,If both a and b are 1-D arrays, it is inner product of vectors (without complex conjugation).If both a and b ar...
